CVE-2026-98085
The Linux kernel contains a vulnerability in the BPF precision backtracking mechanism affecting BPF_LD | BPF_{IND,ABS} instructions. The root cause is that the backtrack_insn() function fails to handle the implicit exit case from a subprogram. Specifically, it does not call bt_subprog_enter() whe...
