In the Linux kernel, the following vulnerability has been resolved:
watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger
When the cpu5wdt module is removing, the origin code uses del_timer() to
de-activate the timer. If the timer handler is running, del_timer() could
not stop it and will return directly. If the port region is released by
release_region() and then the timer handler cpu5wdt_trigger() calls outb()
to write into the region that is released, the use-after-free bug will
happen.
Change del_timer() to timer_shutdown_sync() in order that the timer handler
could be finished before the port region is released.

Kernel Live Patch Security Notice
In the Linux kernel, the following vulnerability has been
resolved: tls: fix use-after-free on failed backlog decryption When the
decrypt request goes to the backlog and crypto_aead_decrypt returns -EBUSY,
tls_do_decryption will wait until all async decryptions have completed. If
one of them fails, tls_do_decryption will return -EBADMSG and
tls_decrypt_sg jumps to the error path, releasing all the pages. But the
pages have been passed to the async callback, and have already been
released by tls_decrypt_done. The only true async case is when
crypto_aead_decrypt returns -EINPROGRESS. With -EBUSY, we already waited so
we can tell tls_sw_recvmsg that the data is available for immediate copy,
but we need to notify tls_decrypt_sg (via the new ->async_done flag)

In the Linux kernel, the following vulnerability has been
resolved: inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released. This affects skb fragments
reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c,
when run as part of tx pipeline. Eric Dumazet made an initial analysis of
this bug. Quoting Eric: Calling ip_defrag() in output path is also implying
skb_orphan(), which is buggy because output path relies on sk not
disappearing. A relevant old patch about the issue was : 8282f27449bf
('inet: frag: Always orphan skbs inside ip_defrag()') [..

CVE-2024-38630 Kernel Live Patch Security Notice
Title: Kernel Live Patch Security Notice
Summary: Several security issues were fixed in the kernel.
In the Linux kernel, the following vulnerability has been
resolved: inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released. This affects skb fragments
reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c,
when run as part of tx pipeline. Eric Dumazet made an initial analysis of
this bug. Quoting Eric: Calling ip_defrag() in output path is also implying
skb_orphan(), which is buggy because output path relies on sk not
disappearing. A relevant old patch about the issue was : 8282f27449b

In the Linux kernel, the following vulnerability has been resolved:
watchdog: cpu5wdt.c: Fix use-after-free bug caused by cpu5wdt_trigger
When the cpu5wdt module is removing, the origin code uses del_timer() to
de-activate the timer. If the timer handler is running, del_timer() could
not stop it and will return directly. If the port region is released by
release_region() and then the timer handler cpu5wdt_trigger() calls outb()
to write into the region that is released, the use-after-free bug will
happen.
Change del_timer() to timer_shutdown_sync() in order that the timer handler
could be finished before the port region is released.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
