CVE-2026-45967 Details
Description
In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The map_direct_value_addr() function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolve_pseudo_ldimm64() function adds the offset. Fix it. Corresponding selftests are added in a consequent commit.
A vulnerability in the Linux kernel's BPF instruction array map has been addressed. The issue arose in the 'map_direct_value_addr()' function, which improperly added offsets to the resulting address. This miscalculation was problematic because the 'resolve_pseudo_ldimm64()' function later added the offset again, leading to incorrect address handling. The vulnerability has been fixed, and corresponding self-tests have been added.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the updated kernel can be found on the official Linux kernel website.
