In the Linux kernel, the following vulnerability has been resolved:
dm: fix a crash if blk_alloc_disk fails
If blk_alloc_disk fails, the variable md->disk is set to an error value.
cleanup_mapped_device will see that md->disk is non-NULL and it will
attempt to access it, causing a crash on this statement
"md->disk->private_data = NULL;".

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.

CVE-2024-50277 [MEDIUM] CWE-476 kernel: dm: fix a crash if blk_alloc_disk fails
kernel: dm: fix a crash if blk_alloc_disk fails
In the Linux kernel, the following vulnerability has been resolved:
dm: fix a crash if blk_alloc_disk fails
If blk_alloc_disk fails, the variable md->disk is set to an error value.
cleanup_mapped_device will see that md->disk is non-NULL and it will
attempt to access it, causing a crash on this statement
"md->disk->private_data = NULL;".
Statement: The issue is that possible Null pointer dereference if device initialization fails. The security impact is limited, because attacker cannot control it (means hard to trigger fail path during boot or during other special case of device initialization and after that hard to use Null pointer dereference for anything apart from deny of service).

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.
