In the Linux kernel, the following vulnerability has been resolved:
mptcp: init: protect sched with rcu_read_lock
Enabling CONFIG_PROVE_RCU_LIST with its dependence CONFIG_RCU_EXPERT
creates this splat when an MPTCP socket is created:
WARNING: suspicious RCU usage
6.12.0-rc2+ #11 Not tainted
net/mptcp/sched.c:44 RCU-list traversed in non-reader section!!
other info that might help us debug this:
rcu_scheduler_active = 2, debug_locks = 1
no locks held by mptcp_connect/176.
stack backtrace:
CPU: 0 UID: 0 PID: 176 Comm: mptcp_connect Not tainted 6.12.0-rc2+ #11
Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011

That's because when the socket is initialised, rcu_read_lock() is not
used despite the explicit comment written above the declaration of
mptcp_sched_find() in sched.c. Adding the missing lock/unlock avoids the
warning.

CVE-2024-47738 Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM32 architecture;
- ARM64 architecture;
- PowerPC architecture;
- RISC-V architecture;
- S390 architecture;
- SuperH RISC architecture;
- User-Mode Linux (UML);
- x86 architecture;
- Block layer subsystem;

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.
