Improper locking in Linux kernel - CVE-2024-27034

Vulnerability identifier: #VU93785

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-2024-27034

CWE-ID: CWE-667

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 improper locking within the f2fs_write_single_data_page() function in fs/f2fs/data.c, within the f2fs_compress_write_end_io(), f2fs_write_raw_pages() and unlock_page() functions in fs/f2fs/compress.c. A local user can perform a denial of service (DoS) attack.
