In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix implicit ODP use after free
Prevent double queueing of implicit ODP mr destroy work by using
__xa_cmpxchg() to make sure this is the only time we are destroying this
specific mr.
Without this change, we could try to invalidate this mr twice, which in
turn could result in queuing a MR work destroy twice, and eventually the
second work could execute after the MR was freed due to the first work,
causing a user after free and trace below.
refcount_t: underflow; use-after-free.

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.

CVE-2025-2312 [MEDIUM] linux-hwe-6.8 vulnerabilities
linux-hwe-6.8 vulnerabilities
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly verify the target namespace when handling
upcalls. An attacker could use this to expose sensitive information.

CVE-2025-21714 [HIGH] CWE-416 GHSA-3g4q-gv3v-9pj2: In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix implicit ODP use after free
Prevent double queueing of implicit O
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix implicit ODP use after free
Prevent double queueing of implicit ODP mr destroy work by using
__xa_cmpxchg() to make sure this is the only time we are destroying this
specific mr.
Without this change, we could try to invalidate this mr twice, which in
turn could result in queuing a MR work destroy twice, and eventually the
second work could execute after the MR was freed due to the first work,
causing a user after free and trace below.
refcount_t: underflow; use-after-free.
