In the Linux kernel, the following vulnerability has been resolved:
can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open
The mcp251x_hw_wake() function is called with the mpc_lock mutex held and
disables the interrupt handler so that no interrupts can be processed while
waking the device. If an interrupt has already occurred then waiting for
the interrupt handler to complete will deadlock because it will be trying
to acquire the same mutex.

mcp251x_can_ist()
mutex_lock(&priv->mcp_lock)
mcp251x_hw_wake()
disable_irq() <-- deadlock
Use disable_irq_nosync() instead because the interrupt handler does
everything while holding the mutex so it doesn't matter if it's still
running.

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-2024-25744 [HIGH] linux-aws vulnerabilities
linux-aws vulnerabilities
Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and
Shweta Shinde discovered that the Confidential Computing framework in
the Linux kernel for x86 platforms did not properly handle 32-bit
emulation on TDX and SEV. An attacker with access to the VMM could use
this to cause a denial of service (guest crash) or possibly execute
arbitrary code. (CVE-2024-25744)
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:
- ARM64 architecture;
- MIPS architecture;
- PowerPC architecture;
- RISC-V architecture;
- User-Mode Linux (UML);
- x86 architecture;
- Block layer subsystem;
- Android drivers;
- Serial ATA and Parallel ATA drive

In the Linux kernel, the following vulnerability has been resolved:
can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open
The mcp251x_hw_wake() function is called with the mpc_lock mutex held and
disables the interrupt handler so that no interrupts can be processed while
waking the device. If an interrupt has already occurred then waiting for
the interrupt handler to complete will deadlock because it will be trying
to acquire the same mutex.

Use disable_irq_nosync() instead because the interrupt handler does
everything while holding the mutex so it doesn't matter if it's still
running.
