In the Linux kernel, the following vulnerability has been resolved:
ublk: detach gendisk from ublk device if add_disk() fails
Inside ublk_abort_requests(), gendisk is grabbed for aborting all
inflight requests. And ublk_abort_requests() is called when exiting
the uring context or handling timeout.
If add_disk() fails, the gendisk may have been freed when calling
ublk_abort_requests(), so use-after-free can be caused when getting
disk's reference in ublk_abort_requests().
Fixes the bug by detaching gendisk from ublk device if add_disk() fails.

Title: Linux kernel (Low Latency) 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.

kernel: ublk: detach gendisk from ublk device if add_disk() fails
vendor_redhat·2025-01-06·CVSS 7.8
CVE-2024-56764 [HIGH] CWE-416 kernel: ublk: detach gendisk from ublk device if add_disk() fails
kernel: ublk: detach gendisk from ublk device if add_disk() fails
In the Linux kernel, the following vulnerability has been resolved:
ublk: detach gendisk from ublk device if add_disk() fails
Inside ublk_abort_requests(), gendisk is grabbed for aborting all
inflight requests. And ublk_abort_requests() is called when exiting
the uring context or handling timeout.
If add_disk() fails, the gendisk may have been freed when calling
ublk_abort_requests(), so use-after-free can be caused when getting
disk's reference in ublk_abort_requests().
Fixes the bug by detaching gendisk from ublk device if add_disk() fails.
