The disclosed bytes are converted into the username and domain strings that reach ksmbd.mountd and the kernel log, and the domain string feeds the NTLMv2 HMAC comparison, forming a remote oracle for recovering adjacent heap contents.\nI:N - Every consumer of the mis-sized buffer was traced and all are reads; the only writes (conn-\u003entlmssp.client_flags, sess-\u003esess_key via cifs_arc4_crypt bounded by CIFS_KEY_SIZE, and the kzalloc\u0027d construct buffer) target correctly sized in-bounds destinations, so no out-of-bounds write or control-flow primitive exists.\nA:H - The attacker-chosen read offset of up to 65535 bytes past a kmalloc-8/kmalloc-96 object will readily walk off the end of the slab page into unmapped or poisoned memory, oopsing the ksmbd worker thread (and panicking immediately under KASAN/DEBUG_PAGEALLOC), and it can be retriggered on a fresh unauthenticated connection at will."

Title
KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache
Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache
There is a potential UAF scenario in the case of an LPI translation
cache hit racing with an operation that invalidates the cache, such
as a DISCARD ITS command. The root of the problem is that
vgic_its_check_cache() does not elevate the refcount on the vgic_irq
before dropping the lock that serializes refcount changes.
Have vgic_its_check_cache() raise the refcount on the returned vgic_irq
and add the corresponding decrement after queueing the interrupt.

Title
phy: ti: phy-omap-usb2: Fix NULL pointer dereference for SRP
Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: ti: phy-omap-usb2: Fix NULL pointer dereference for SRP
If the external phy working together with phy-omap-usb2 does not implement
send_srp(), we may still attempt to call it. This can happen on an idle
Ethernet gadget triggering a wakeup for example:
configfs-gadget.g1 gadget.0: ECM Suspend
configfs-gadget.g1 gadget.0: Port suspended. Triggering wakeup
...
Unable to handle kernel NULL pointer dereference at virtual address
00000000 when execute
...
PC is at 0x0
LR is at musb_gadget_wakeup+0x1d4/0x254 [musb_hdrc]

udp_sendmsg from __sys_sendto+0xd8/0x158
__sys_sendto from ret_fast_syscall+0x0/0x58
Let's fix the issue by checking for send_srp() and set_vbus() before
calling them. For USB peripheral only cases these both could be NULL.

Title
sched/membarrier: reduce the ability to hammer on sys_membarrier
Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/membarrier: reduce the ability to hammer on sys_membarrier
On some systems, sys_membarrier can be very expensive, causing overall
slowdowns for everything. So put a lock on the path in order to
serialize the accesses to prevent the ability for this to be called at
too high of a frequency and saturate the machine.

Title
binder: signal epoll threads of self-work
Summary
In the Linux kernel, the following vulnerability has been resolved:
binder: signal epoll threads of self-work
In (e)poll mode, threads often depend on I/O events to determine when
data is ready for consumption. Within binder, a thread may initiate a
command via BINDER_WRITE_READ without a read buffer and then make use
of epoll_wait() or similar to consume any responses afterwards.
It is then crucial that epoll threads are signaled via wakeup when they
queue their own work. Otherwise, they risk waiting indefinitely for an
event leaving their work unhandled. What is worse, subsequent commands
won't trigger a wakeup either as the thread has pending work.

ksmbd: fix global oob in ksmbd_nl_policy
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix global oob in ksmbd_nl_policy
Similar to a reported issue (check the commit b33fb5b801c6 ("net:
qualcomm: rmnet: fix global oob in rmnet_policy"), my local fuzzer finds
another global out-of-bounds read for policy ksmbd_nl_policy. See bug

To fix it, add a placeholder named __KSMBD_EVENT_MAX and let
KSMBD_EVENT_MAX to be its original value - 1 according to what other
netlink families do. Also change two sites that refer the
KSMBD_EVENT_MAX to correct value.

Title
wifi: iwlwifi: fix a memory corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix a memory corruption
iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.

Reaching the vulnerable merge requires local presence on the system (module/firmware load or the debugfs time-point/clear handlers), so this is Local rather than Adjacent.\nAC:L - The out-of-bounds write is fully deterministic \u2014 whenever two triggers share a time point and the newer one lacks IWL_FW_INI_APPLY_POLICY_OVERRIDE_DATA with non-empty existing data, the byte offset is unconditionally multiplied by four. There is no race, no memory-layout precondition, and INI debug is enabled by default, so no unusual configuration is needed.\nPR:L - Triggering requires only local access to the code path that (re)initializes the iwlwifi firmware debug configuration, with no authentication step in the path itself and no capability check inside iwl_dbg_tlv_override_trig_node. Between low and high privileges this is scored as the higher-severity Low, consistent with other locally-triggered iwlwifi memory-corruption CVEs.\nUI:N - No victim action is required \u2014 the trigger list is merged automatically at IWL_FW_INI_TIME_POINT_EARLY during normal firmware load, which occurs at boot or whenever the device is brought up.\nS:U - The overflow corrupts kernel slab memory and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The heap overflow writes past the krealloc\u0027d node into adjacent slab objects, corrupting neighbouring kernel structures such as pointers and length fields, which can be leveraged into an arbitrary kernel read primitive and disclosure of arbitrary memory.\nI:H - This is an out-of-bounds heap write of attacker-influenced content whose length (roughly 3 x data_len) and payload both come from the trigger TLV, giving a shaped write into adjacent slab objects \u2014 the standard primitive for kernel data/control-flow corruption and privilege escalation.\nA:H - Slab corruption of adjacent objects reliably produces kernel oopses, allocator BUG_ON/hardened-usercopy panics, or later crashes on freeing the smashed neighbours, resulting in a complete denial of service."

Title
net/smc: fix illegal rmb_desc access in SMC-D connection dump
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix illegal rmb_desc access in SMC-D connection dump
A crash was found when dumping SMC-D connections. It can be reproduced
by following steps:
- run nginx/wrk test:
smc_run nginx
smc_run wrk -t 16 -c 1000 -d <duration> -H 'Connection: Close' <URL>
- continuously dump SMC-D connections in parallel:
watch -n 1 'smcss -D'
BUG: kernel NULL pointer dereference, address: 0000000000000030

It is possible that the connection is in process of being established
when we dump it. Assumed that the connection has been registered in a
link group by smc_conn_create() but the rmb_desc has not yet been
initialized by smc_buf_create(), thus causing the illegal access to
conn->rmb_desc. So fix it by checking before dump.

Title
tomoyo: fix UAF write bug in tomoyo_write_control()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: fix UAF write bug in tomoyo_write_control()
Since tomoyo_write_control() updates head->write_buf when write()
of long lines is requested, we need to fetch head->write_buf after
head->io_sem is held. Otherwise, concurrent write() requests can
cause use-after-free-write and double-free problems.
Severity
No CVSS data available.
