Improper error handling in Linux kernel - CVE-2024-26706

Vulnerability identifier: #VU92945

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-2024-26706

CWE-ID: CWE-388

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 error handling within the fixup_exception() function in arch/parisc/mm/fault.c, within the emulate_ldh(), emulate_ldw(), emulate_ldd(), emulate_sth(), emulate_stw() and emulate_std() functions in arch/parisc/kernel/unaligned.c. A local user can perform a denial of service (DoS) attack.
