In the Linux kernel, the following vulnerability has been resolved:
net: dev_ioctl: take ops lock in hwtstamp lower paths
ndo hwtstamp callbacks are expected to run under the per-device ops
lock. Make the lower get/set paths consistent with the rest of ndo
invocations.

Note that the mlx5_hwtstamp_set and mlx5e_hwtstamp_set functions shown
in the trace come from an in progress patch converting the legacy ioctl
to ndo_hwtstamp_get/set and are not present in mainline.

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.

It was discovered that Ruby incorrectly handled parsing of an XML document
that has specific XML characters in an attribute value using REXML gem. An
attacker could use this issue to cause Ruby to crash, resulting in a
denial of service. This issue only affected in Ubuntu 22.04 LTS, Ubuntu
24.04 LTS, and Ubuntu 24.10. (CVE-2024-35176, CVE-2024-39908,
CVE-2024-41123, CVE-2024-43398)
It was discovered that Ruby incorrectly handled expanding ranges in the
net-imap response parser. If a user or automated system were tricked into
connecting to a malicious IMAP server, a remote attacker could possibly use
this issue to consume memory, leading to a denial of service. This issue
only affected Ubuntu 24.04 LTS, and Ubuntu 24.10. (CVE-2025-25186)
