Title
bpf: make sure skb->len != 0 when redirecting to a tunneling device
Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: make sure skb->len != 0 when redirecting to a tunneling device
syzkaller managed to trigger another case where skb->len == 0
when we enter __dev_queue_xmit:
WARNING: CPU: 0 PID: 2470 at include/linux/skbuff.h:2576 skb_assert_len include/linux/skbuff.h:2576 [inline]

The reproducer doesn't really reproduce outside of syzkaller
environment, so I'm taking a guess here. It looks like we
do generate correct ETH_HLEN-sized packet, but we redirect
the packet to the tunneling device. Before we do so, we
__skb_pull l2 header and arrive again at skb->len == 0.
Doesn't seem like we can do anything better than having
an explicit check after __skb_pull?

Title
scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()
The function lio_target_nacl_info_show() uses sprintf() in a loop to print
details for every iSCSI connection in a session without checking for the
buffer length. With enough iSCSI connections it's possible to overflow the
buffer provided by configfs and corrupt the memory.
This patch replaces sprintf() with sysfs_emit_at() that checks for buffer
boundries.

Title
tcp: correct handling of extreme memory squeeze
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: correct handling of extreme memory squeeze
Testing with iperf3 using the "pasta" protocol splicer has revealed
a problem in the way tcp handles window advertising in extreme memory
squeeze situations.
Under memory pressure, a socket endpoint may temporarily advertise
a zero-sized window, but this is not stored as part of the socket data.
The reasoning behind this is that it is considered a temporary setting
which shouldn't influence any further calculations.
However, if we happen to stall at an unfortunate value of the current
window size, the algorithm selecting a new value will consistently fail
to advertise a non-zero window once we have freed up enough memory.
This means that this side's notion of the current window size is
different from the one last advertised to the peer, causing the latter
to not send any data to resolve the sitution.
The problem occurs on the iperf3 server side, and the socket in question
is a completely regular socket with the default settings for the
fedora40 kernel. We do not use SO_PEEK or SO_RCVBUF on the socket.
The following excerpt of a logging session, with own comments added,
shows more in detail what is happening:

Any routable TCP service \u2014 HTTP, SSH, ksmbd, nfsd, database \u2014 is reachable over the network.\nAC:L - The attacker controls both preconditions: skb truesize amplification lets a flood of small segments exhaust `sk_rmem_alloc`/`tcp_mem` while consuming little sequence space, which reliably leaves `tcp_receive_window()` above half the maximum at squeeze time \u2014 exactly the state that makes the `new_window \u003e= 2 * rcv_window_now` test in `__tcp_cleanup_rbuf()` permanently unsatisfiable \u2014 and the attacker then simply declines to send zero-window probes, which is the only recovery path.\nPR:N - No authentication or privilege is needed; the condition is reached in `tcp_data_queue()` on established connections before any application-layer authentication, so any unauthenticated client of any TCP listener can drive it.\nUI:N - Triggering requires only that the target socket receive attacker-supplied data; no action by a local user or administrator is involved.\nS:U - The inconsistent window state and the resulting stall are confined to the kernel TCP stack and the sockets it owns, with no crossing of a security authority boundary.\nC:N - No uninitialized, out-of-bounds, or freed memory is read or transmitted; the defect is limited to bookkeeping of `tp-\u003ercv_wnd`/`tp-\u003ercv_wup` and produces no disclosure of kernel or other sockets\u0027 data.\nI:L - The attacker causes the connection\u0027s protocol state to be left incorrect \u2014 the stored receive window diverges from what was advertised, and the fix explicitly notes the pre-fix path transmits regressing `th-\u003eack_seq` values that are \"wrong from a protocol viewpoint\" \u2014 pinning the peer\u0027s `snd_wnd` at a bogus zero; the modification is bounded and its consequences are not attacker-directed.\nA:H - The connection enters a permanent deadlock \u2014 the receive queue empties but no window update is ever sent and the peer never transmits again \u2014 indefinitely pinning a socket and, for blocking servers, a worker thread; repeated across many connections this exhausts a server\u0027s connection and thread pools, and TCP keepalive is disabled by default so nothing breaks the stall."

Title
pds_core: remove write-after-free of client_id
Summary
In the Linux kernel, the following vulnerability has been resolved:
pds_core: remove write-after-free of client_id
A use-after-free error popped up in stress testing:
[Mon Apr 21 21:21:33 2025] BUG: KFENCE: use-after-free write in pdsc_auxbus_dev_del+0xef/0x160 [pds_core]
[Mon Apr 21 21:21:33 2025] Use-after-free write at 0x000000007013ecd1 (in kfence-#47):
[Mon Apr 21 21:21:33 2025] pdsc_auxbus_dev_del+0xef/0x160 [pds_core]
[Mon Apr 21 21:21:33 2025] pdsc_remove+0xc0/0x1b0 [pds_core]
[Mon Apr 21 21:21:33 2025] pci_device_remove+0x24/0x70
[Mon Apr 21 21:21:33 2025] device_release_driver_internal+0x11f/0x180
[Mon Apr 21 21:21:33 2025] driver_detach+0x45/0x80
[Mon Apr 21 21:21:33 2025] bus_remove_driver+0x83/0xe0
[Mon Apr 21 21:21:33 2025] pci_unregister_driver+0x1a/0x80
The actual device uninit usually happens on a separate thread
scheduled after this code runs, but there is no guarantee of order
of thread execution, so this could be a problem. There's no
actual need to clear the client_id at this point, so simply
remove the offending code.
Severity

s390/mm: Fix in_atomic() handling in do_secure_storage_access()
Summary
In the Linux kernel, the following vulnerability has been resolved:
s390/mm: Fix in_atomic() handling in do_secure_storage_access()
Kernel user spaces accesses to not exported pages in atomic context
incorrectly try to resolve the page fault.
With debug options enabled call traces like this can be seen:

It is not allowed to take the mmap_lock while in atomic context. Therefore
handle such a secure storage access fault as if the accessed page is not
mapped: the uaccess function will return -EFAULT, and the caller has to
deal with this. Usually this means that the access is retried in process
context, which allows to resolve the page fault (or in this case export the
page).

Title
scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE
On Google gs101, the number of UTP transfer request slots (nutrs) is 32,
and in this case the driver ends up programming the UTRL_NEXUS_TYPE
incorrectly as 0.
This is because the left hand side of the shift is 1, which is of type
int, i.e. 31 bits wide. Shifting by more than that width results in
undefined behaviour.
Fix this by switching to the BIT() macro, which applies correct type
casting as required. This ensures the correct value is written to
UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift
warning:
UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21
shift exponent 32 is too large for 32-bit type 'int'
For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE
write.

Title
net: macb: fix unregister_netdev call order in macb_remove()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: macb: fix unregister_netdev call order in macb_remove()
When removing a macb device, the driver calls phy_exit() before
unregister_netdev(). This leads to a WARN from kernfs:
------------[ cut here ]------------
kernfs: can not remove 'attached_dev', no directory
WARNING: CPU: 1 PID: 27146 at fs/kernfs/dir.c:1683
Call trace:
kernfs_remove_by_name_ns+0xd8/0xf0
sysfs_remove_link+0x24/0x58
phy_detach+0x5c/0x168
phy_disconnect+0x4c/0x70
phylink_disconnect_phy+0x6c/0xc0 [phylink]
macb_close+0x6c/0x170 [macb]
...
macb_remove+0x60/0x168 [macb]
platform_remove+0x5c/0x80
...
The warning happens because the PHY is being exited while the netdev
is still registered. The correct order is to unregister the netdev
before shutting down the PHY and cleaning up the MDIO bus.
Fix this by moving unregister_netdev() ahead of phy_exit() in
macb_remove().

Title
fs/smb: Fix inconsistent refcnt update
Summary
In the Linux kernel, the following vulnerability has been resolved:
fs/smb: Fix inconsistent refcnt update
A possible inconsistent update of refcount was identified in `smb2_compound_op`.
Such inconsistent update could lead to possible resource leaks.
Why it is a possible bug:
1. In the comment section of the function, it clearly states that the
reference to `cfile` should be dropped after calling this function.
2. Every control flow path would check and drop the reference to
`cfile`, except the patched one.
3. Existing callers would not handle refcount update of `cfile` if
-ENOMEM is returned.
To fix the bug, an extra goto label "out" is added, to make sure that the
cleanup logic would always be respected. As the problem is caused by the
allocation failure of `vars`, the cleanup logic between label "finished"
and "out" can be safely ignored. According to the definition of function
`is_replayable_error`, the error code of "-ENOMEM" is not recoverable.
Therefore, the replay logic also gets ignored.
Severity
No CVSS data available.

In the comment section of the function, it clearly states that the\nreference to `cfile` should be dropped after calling this function.\n2. Every control flow path would check and drop the reference to\n`cfile`, except the patched one.\n3. Existing callers would not handle refcount update of `cfile` if\n-ENOMEM is returned.\n\nTo fix the bug, an extra goto label \"out\" is added, to make sure that the\ncleanup logic would always be respected. As the problem is caused by the\nallocation failure of `vars`, the cleanup logic between label \"finished\"\nand \"out\" can be safely ignored. According to the definition of function\n`is_replayable_error`, the error code of \"-ENOMEM\" is not recoverable.\nTherefore, the replay logic also gets ignored."

Title
io_uring/kbuf: fix signedness in this_len calculation
Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/kbuf: fix signedness in this_len calculation
When importing and using buffers, buf->len is considered unsigned.
However, buf->len is converted to signed int when committing. This can
lead to unexpected behavior if the buffer is large enough to be
interpreted as a negative value. Make min_t calculation unsigned.
