Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
sctp: handle the error returned from sctp_auth_asoc_init_active_key
When it returns an error from sctp_auth_asoc_init_active_key(), the
active_key is actually not updated. The old sh_key will be freeed
while it's still used as active key in asoc. Then an use-after-free
will be triggered when sending patckets, as found by syzbot:
sctp_auth_shkey_hold+0x22/0xa0 net/sctp/auth.c:112
sctp_set_owner_w net/sctp/socket.c:132 [inline]
sctp_sendmsg_to_asoc+0xbd5/0x1a20 net/sctp/socket.c:1863
sctp_sendmsg+0x1053/0x1d50 net/sctp/socket.c:2025
inet_sendmsg+0x99/0xe0 net/ipv4/af_inet.c:819
sock_sendmsg_nosec net/socket.c:714 [inline]
sock_sendmsg+0xcf/0x120 net/socket.c:734
This patch is to fix it by not replacing the sh_key when it returns
errors from sctp_auth_asoc_init_active_key() in sctp_auth_set_key().
For sctp_auth_set_active_key(), old active_key_id will be set back
to asoc->active_key_id when the same thing happens.

In the Linux kernel, the following vulnerability has been resolved:
cxl: fix possible null-ptr-deref in cxl_pci_init_afu|adapter()
If device_register() fails in cxl_pci_afu|adapter(), the device
is not added, device_unregister() can not be called in the error
path, otherwise it will cause a null-ptr-deref because of removing
not added device.
As comment of device_register() says, it should use put_device() to give
up the reference in the error path. So split device_unregister() into
device_del() and put_device(), then goes to put dev when register fails.

In the Linux kernel, the following vulnerability has been resolved:
rapidio: fix possible UAF when kfifo_alloc() fails
If kfifo_alloc() fails in mport_cdev_open(), goto err_fifo and just free
priv. But priv is still in the chdev->file_list, then list traversal
may cause UAF. This fixes the following smatch warning:
drivers/rapidio/devices/rio_mport_cdev.c:1930 mport_cdev_open() warn: '&priv->list' not removed from list

In the Linux kernel, the following vulnerability has been resolved:
io_uring/af_unix: defer registered files gc to io_uring release
Instead of putting io_uring's registered files in unix_gc() we want it
to be done by io_uring itself. The trick here is to consider io_uring
registered files for cycle detection but not actually putting them down.
Because io_uring can't register other ring instances, this will remove
all refs to the ring file triggering the ->release path and clean up
with io_ring_ctx_free().

In the Linux kernel, the following vulnerability has been resolved:
lib/crypto: arm/poly1305: Fix register corruption in no-SIMD contexts
Restore the SIMD usability check that was removed by commit 773426f4771b
("crypto: arm/poly1305 - Add block-only interface").
This safety check is cheap and is well worth eliminating a footgun.
While the Poly1305 functions should not be called when SIMD registers
are unusable, if they are anyway, they should just do the right thing
instead of corrupting random tasks' registers and/or computing incorrect
MACs. Fixing this is also needed for poly1305_kunit to pass.
Just use may_use_simd() instead of the original crypto_simd_usable(),
since poly1305_kunit won't rely on crypto_simd_disabled_for_test.

In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Remove WARN_ON_ONCE() call from ufshcd_uic_cmd_compl()
The UIC completion interrupt may be disabled while an UIC command is
being processed. When the UIC completion interrupt is reenabled, an UIC
interrupt is triggered and the WARN_ON_ONCE(!cmd) statement is hit.
Hence this patch that removes this kernel warning.
