NULL pointer dereference in Linux kernel - CVE-2023-53044

Vulnerability identifier: #VU108465

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2023-53044

CWE-ID: CWE-476

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to NULL pointer dereference within the alloc_dev() function in drivers/md/dm.c, within the dm_stat_in_flight() and dm_stats_init() functions in drivers/md/dm-stats.c. A local user can perform a denial of service (DoS) attack.
