When hfsplus_uni2asc is called from hfsplus_listxattr,
it actually passes in a struct hfsplus_attr_unistr*.
The size of the corresponding structure is different from that of hfsplus_unistr,
so the previous fix (94458781aee6) is insufficient.
The pointer on the unicode buffer is still going beyond the allocated memory.
This patch introduces two warpper functions hfsplus_uni2asc_xattr_str and
hfsplus_uni2asc_str to process two unicode buffers,
struct hfsplus_attr_unistr* and struct hfsplus_unistr* respectively.
When ustrlen value is bigger than the allocated memory size,
the ustrlen value is limited to an safe size.

"value": "AV:L - The attacker-controlled input is an on-disk HFS+ attributes B-tree key, and the vulnerable conversion is reached through the ordinary local `listxattr()`/`llistxattr()` syscall on a mounted volume; there is no network or remote-peer input path. Local rather than Physical because the volume can be attached locally via a loop device and the trigger is a plain local syscall.\nAC:L - The `length` field of the `hfsplus_attr_unistr` key name is written verbatim by the attacker in the crafted image and was clamped to 255 instead of 127, so the 256-byte overread fires deterministically on the first `listxattr()` call. No race, no heap grooming, and no condition outside the attacker\u0027s control.\nPR:L - Nothing on the `path_listxattrat` \u2192 `vfs_listxattr` \u2192 `hfsplus_listxattr` \u2192 `hfsplus_uni2asc` path performs any capability check \u2014 the only `capable(CAP_SYS_ADMIN)` test (`can_list()`) runs after the out-of-bounds conversion and merely filters `trusted.*` names. Any unprivileged local user who can traverse an HFS+ volume (e.g. one udisks2-automounted from attacker-supplied removable media) triggers it.\nUI:N - In the automount/kiosk scenario the volume is mounted by the system on device insertion with no victim action, and the attacker then issues the `listxattr()` himself; likewise an attacker with loop-mount access performs every step. Choosing the higher-severity option where the mount could otherwise be attributed to a victim.\nS:U - The out-of-bounds read, the leaked bytes, and any resulting fault all stay within the kernel\u0027s own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is not a bounded few-byte read: up to 256 bytes past the `kzalloc(536)` key allocation are consumed, NLS-converted into `strbuf`, and copied out to userspace by `copy_name()` plus the `copy_to_user()` in `listxattr()`, giving a direct kernel-heap disclosure channel rather than a mere oracle. On slub_debug/KASAN/KFENCE and hardened configurations those bytes are live redzone/stale slab content adjacent to the allocation.\nI:N - `hfsplus_uni2asc()` only dereferences and converts the input; the output writes are bounded by `*len_p` via `nls-\u003euni2char()` returning `-ENAMETOOLONG`. There is no out-of-bounds write, no type confusion, and no mechanism to modify kernel memory or hijack control flow.\nA:H - The slab out-of-bounds read is a guaranteed KASAN/KFENCE report and, with `panic_on_warn`/`panic_on_oops`, a kernel panic; where the overread crosses a KFENCE guard page it faults outright. It also leaves the xattr listing returning `-EIO`/garbage, rendering the volume\u0027s attribute handling unusable, and is repeatable at will by an unprivileged user."

Title
tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: Use __sk_dst_get() and dst_dev_rcu() in get_netdev_for_sock().
get_netdev_for_sock() is called during setsockopt(),
so not under RCU.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the only ->ndo_sk_get_lower_dev() user is
bond_sk_get_lower_dev(), which uses RCU.

The racing `dst_dev_put()` side likewise requires local netlink link/route teardown, so the entire attack is delivered through local syscalls.\nAC:L - The attacker controls both sides of the race \u2014 one thread repeatedly issues `setsockopt(TLS_TX)` on TCP sockets whose `sk_dst_cache` points at a veth while another deletes that veth in the attacker\u0027s own netns \u2014 and can retry indefinitely until the window between reading `dst-\u003edev` and the `netdev_ref_replace()`/free is hit. `CONFIG_TLS_DEVICE` is a routinely enabled distro option, and the vulnerable read happens before any NIC-capability or `IFF_UP` gate, so no special hardware is required.\nPR:L - An ordinary unprivileged local account suffices: attaching the tls ULP and calling `setsockopt(SOL_TLS, ...)` requires no capability once the ULP is registered (the `capable(CAP_NET_ADMIN)` check in `__tcp_ulp_find_autoload()` gates only module autoload), and the CAP_NET_ADMIN needed to create and delete the veth is obtained in the attacker\u0027s own user+net namespace via `unshare -Urn`, not real root.\nUI:N - Exploitation is driven entirely by the attacker\u0027s own threads issuing socket syscalls and netlink link/route operations; no victim action, mount, or file open is involved.\nS:U - The use-after-free is on a kernel `struct net_device` and its consequences remain within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on a freed, heap-sprayable `net_device`: `netdev_sk_get_lower_dev()` reads `dev-\u003enetdev_ops` from freed memory and the caller subsequently reads `netdev-\u003efeatures` and `netdev-\u003eflags`, whose values are observable through the setsockopt return code and the resulting offload state, giving an attacker-groomable read of reclaimed kernel memory.\nI:H - The freed object is used for two indirect calls \u2014 `ops-\u003endo_sk_get_lower_dev(dev, sk)` and later `netdev-\u003etlsdev_ops-\u003etls_dev_add(...)` \u2014 both function pointers loaded out of reclaimed memory, and `dev_hold(lowest_dev)` performs a refcount increment inside the freed allocation, together yielding control-flow-hijack and write primitives once the slab is sprayed.\nA:H - Dereferencing and indirect-calling through a freed `net_device` reliably oopses the kernel even when not weaponized, and the race is repeatable at will by an unprivileged local user for a persistent denial of service."

Title
exfat: fix refcount leak in exfat_find
Summary
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix refcount leak in exfat_find
Fix refcount leaks in `exfat_find` related to `exfat_get_dentry_set`.
Function `exfat_get_dentry_set` would increase the reference counter of
`es->bh` on success. Therefore, `exfat_put_dentry_set` must be called
after `exfat_get_dentry_set` to ensure refcount consistency. This patch
relocate two checks to avoid possible leaks.
Severity
No CVSS data available.

Title
btrfs: fix racy bitfield write in btrfs_clear_space_info_full()
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix racy bitfield write in btrfs_clear_space_info_full()
From the memory-barriers.txt document regarding memory barrier ordering
guarantees:
(*) These guarantees do not apply to bitfields, because compilers often
generate code to modify these using non-atomic read-modify-write
sequences. Do not attempt to use bitfields to synchronize parallel
algorithms.
(*) Even in cases where bitfields are protected by locks, all fields
in a given bitfield must be protected by one lock. If two fields
in a given bitfield are protected by different locks, the compiler's
non-atomic read-modify-write sequences can cause an update to one
field to corrupt the value of an adjacent field.
btrfs_space_info has a bitfield sharing an underlying word consisting of
the fields full, chunk_alloc, and flush:
struct btrfs_space_info {
struct btrfs_fs_info * fs_info; /* 0 8 */
struct btrfs_space_info * parent; /* 8 8 */
...
int clamp; /* 172 4 */
unsigned int full:1; /* 176: 0 4 */
unsigned int chunk_alloc:1; /* 176: 1 4 */
unsigned int flush:1; /* 176: 2 4 */
...
Therefore, to be safe from parallel read-modify-writes losing a write to
one of the bitfield members protected by a lock, all writes to all the
bitfields must use the lock. They almost universally do, except for
btrfs_clear_space_info_full() which iterates over the space_infos and
writes out found->full = 0 without a lock.
Imagine that we have one thread completing a transaction in which we
finished deleting a block_group and are thus calling
btrfs_clear_space_info_full() while simultaneously the data reclaim
ticket infrastructure is running do_async_reclaim_data_space():
T1 T2
btrfs_commit_transaction
btrfs_clear_space_info_full
data_sinfo->full = 0
READ: full:0, chunk_alloc:0, flush:1
do_async_reclaim_data_space(data_sinfo)
spin_lock(&space_info->lock);
if(list_empty(tickets))
space_info->flush = 0;
READ: full: 0, chunk_alloc:0, flush:1
MOD/WRITE: full: 0, chunk_alloc:0, flush:0
spin_unlock(&space_info->lock);
return;
MOD/WRITE: full:0, chunk_alloc:0, flush:1
and now data_sinfo->flush is 1 but the reclaim worker has exited. This
breaks the invariant that flush is 0 iff there is no work queued or
running. Once this invariant is violated, future allocations that go
into __reserve_bytes() will add tickets to space_info->tickets but will
see space_info->flush is set to 1 and not queue the work. After this,
they will block forever on the resulting ticket, as it is now impossible
to kick the worker again.
I also confirmed by looking at the assembly of the affected kernel that
it is doing RMW operations. For example, to set the flush (3rd) bit to 0,
the assembly is:
andb $0xfb,0x60(%rbx)
and similarly for setting the full (1st) bit to 0:
andb $0xfe,-0x20(%rax)
So I think this is really a bug on practical systems. I have observed
a number of systems in this exact state, but am currently unable to
reproduce it.
Rather than leaving this footgun lying around for the future, take
advantage of the fact that there is room in the struct anyway, and that
it is already quite large and simply change the three bitfield members to
bools. This avoids writes to space_info->full having any effect on

Title
fs/ntfs3: Initialize allocated memory before use
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Initialize allocated memory before use
KMSAN reports: Multiple uninitialized values detected:
- KMSAN: uninit-value in ntfs_read_hdr (3)
- KMSAN: uninit-value in bcmp (3)
Memory is allocated by __getname(), which is a wrapper for
kmem_cache_alloc(). This memory is used before being properly
cleared. Change kmem_cache_alloc() to kmem_cache_zalloc() to
properly allocate and clear memory before use.

Title
bpf: Do not let BPF test infra emit invalid GSO types to stack
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Do not let BPF test infra emit invalid GSO types to stack
Yinhao et al. reported that their fuzzer tool was able to trigger a
skb_warn_bad_offload() from netif_skb_features() -> gso_features_check().
When a BPF program - triggered via BPF test infra - pushes the packet
to the loopback device via bpf_clone_redirect() then mentioned offload
warning can be seen. GSO-related features are then rightfully disabled.
We get into this situation due to convert___skb_to_skb() setting
gso_segs and gso_size but not gso_type. Technically, it makes sense
that this warning triggers since the GSO properties are malformed due
to the gso_type. Potentially, the gso_type could be marked non-trustworthy
through setting it at least to SKB_GSO_DODGY without any other specific
assumptions, but that also feels wrong given we should not go further
into the GSO engine in the first place.
The checks were added in 121d57af308d ("gso: validate gso_type in GSO
handlers") because there were malicious (syzbot) senders that combine
a protocol with a non-matching gso_type. If we would want to drop such
packets, gso_features_check() currently only returns feature flags via
netif_skb_features(), so one location for potentially dropping such skbs
could be validate_xmit_unreadable_skb(), but then otoh it would be
an additional check in the fast-path for a very corner case. Given
bpf_clone_redirect() is the only place where BPF test infra could emit
such packets, lets reject them right there.

Title
accel/ivpu: Fix race condition when unbinding BOs
Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix race condition when unbinding BOs
Fix 'Memory manager not clean during takedown' warning that occurs
when ivpu_gem_bo_free() removes the BO from the BOs list before it
gets unmapped. Then file_priv_unbind() triggers a warning in
drm_mm_takedown() during context teardown.
Protect the unmapping sequence with bo_list_lock to ensure the BO is
always fully unmapped when removed from the list. This ensures the BO
is either fully unmapped at context teardown time or present on the
list and unmapped by file_priv_unbind().
Severity
7.8 (High)

Title
NFSD: NFSv4 file creation neglects setting ACL
Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: NFSv4 file creation neglects setting ACL
An NFSv4 client that sets an ACL with a named principal during file
creation retrieves the ACL afterwards, and finds that it is only a
default ACL (based on the mode bits) and not the ACL that was
requested during file creation. This violates RFC 8881 section
6.4.1.3: "the ACL attribute is set as given".
The issue occurs in nfsd_create_setattr(), which calls
nfsd_attrs_valid() to determine whether to call nfsd_setattr().
However, nfsd_attrs_valid() checks only for iattr changes and
security labels, but not POSIX ACLs. When only an ACL is present,
the function returns false, nfsd_setattr() is skipped, and the
POSIX ACL is never applied to the inode.
Subsequently, when the client retrieves the ACL, the server finds
no POSIX ACL on the inode and returns one generated from the file's
mode bits rather than returning the originally-specified ACL.

Title
ublk: fix deadlock when reading partition table
Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: fix deadlock when reading partition table
When one process(such as udev) opens ublk block device (e.g., to read
the partition table via bdev_open()), a deadlock[1] can occur:
1. bdev_open() grabs disk->open_mutex
2. The process issues read I/O to ublk backend to read partition table
3. In __ublk_complete_rq(), blk_update_request() or blk_mq_end_request()
runs bio->bi_end_io() callbacks
4. If this triggers fput() on file descriptor of ublk block device, the
work may be deferred to current task's task work (see fput() implementation)
5. This eventually calls blkdev_release() from the same context
6. blkdev_release() tries to grab disk->open_mutex again
7. Deadlock: same task waiting for a mutex it already holds
The fix is to run blk_update_request() and blk_mq_end_request() with bottom
halves disabled. This forces blkdev_release() to run in kernel work-queue
context instead of current task work context, and allows ublk server to make
forward progress, and avoids the deadlock.

Currently nf_tables will traverse the entire table (chain graph), starting
from the entry points (base chains), exploring all possible paths
(chain jumps). But there are cases where we could avoid revalidation.
Consider:
1 input -> j2 -> j3
2 input -> j2 -> j3
3 input -> j1 -> j2 -> j3
Then the second rule does not need to revalidate j2, and, by extension j3,
because this was already checked during validation of the first rule.
We need to validate it only for rule 3.
This is needed because chain loop detection also ensures we do not exceed
the jump stack: Just because we know that j2 is cycle free, its last jump
might now exceed the allowed stack size. We also need to update all
reachable chains with the new largest observed call depth.
Care has to be taken to revalidate even if the chain depth won't be an
issue: chain validation also ensures that expressions are not called from
invalid base chains. For example, the masquerade expression can only be
called from NAT postrouting base chains.
Therefore we also need to keep record of the base chain context (type,
hooknum) and revalidate if the chain becomes reachable from a different
hook location.
