In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fix tailcallreachable rejection for interpreter when jit failed During testing of f263a81451c1 “bpf: Track subprog poke descriptors correctly and fix use-after-free” under various failure conditions, for example, when...

Astra Linux – Vulnerability in Linux 5.10

A out-of-bounds memory read flaw was discovered in the Linux kernel’s BPF subsystem, related to how a user calls the bpftailcall function with a key that is larger than the maxentries of the map. This flaw allows a local user to gain unauthorized access to data...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall operations. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset being s...

CVE-2025-39990

The CVE-2025-39990 issue affects the Linux kernel’s BPF verifier logic: a NULL helper pointer could arise in get_helper_proto due to a disabled config option. The fix marks the tail_call helper as BPF_PTR_POISON since it is unused by design, mitigating the NULL pointer path. Public advisories (SU...
