Improper access control in Linux kernel - CVE-2026-45886

Vulnerability identifier: #VU132604

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-2026-45886

CWE-ID: CWE-284

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper access control in the bpf_xdp_store_bytes helper prototype when verifying BPF programs that use read-only map values. A local user can load a crafted BPF program to cause a denial of service.

The issue is triggered when the third helper argument points to a value from a BPF_F_RDONLY_PROG map.
