Improper locking in Linux kernel - CVE-2024-40918

Vulnerability identifier: #VU94280

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-2024-40918

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 PTR_PAGE_ALIGN_DOWN(), __flush_cache_page(), flush_icache_pages(), pte_needs_flush(), flush_dcache_folio(), purge_kernel_dcache_page_asm(), copy_user_highpage(), __flush_tlb_range(), flush_cache_range(), flush_anon_page() and invalidate_kernel_vmap_range() functions in arch/parisc/kernel/cache.c. A local user can perform a denial of service (DoS) attack.
