Input validation error in Linux kernel - CVE-2022-48944

Vulnerability identifier: #VU96648

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-2022-48944

CWE-ID: CWE-20

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 input validation within the tg_nop(), sched_fork(), sched_post_fork(), set_user_nice(), __setscheduler_params() and sched_init() functions in kernel/sched/core.c, within the copy_process() function in kernel/fork.c. A local user can perform a denial of service (DoS) attack.
