CWE-ID: CWE-20
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to improper input validation within the rseq_get_rseq_cs_ptr_val(), rseq_get_rseq_cs(), rseq_need_restart(), clear_rseq_cs(), rseq_ip_fixup() and SYSCALL_DEFINE4() functions in kernel/rseq.c. A local user can perform a denial of service (DoS) attack.
