CVE-2026-53081

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs due to inconsistent base ID mapping when the regsafe function compares scalar registers with BPFADDCONST values. This inconsistency allows the BPF verifier to incorrectly succeed in state pruning...

In the Linux kernel, the following vulnerability has been resolved: bpf: Enforce regsafe base id consistency for BPFADDCONST scalars When regsafe compares two scalar registers that both carry BPFADDCONST, checkscalarids maps their full compound id aka base | BPFADDCONST flag as one idmap entry...

DEBIAN-CVE-2022-49961

In the Linux kernel, the following vulnerability has been resolved: bpf: Do markchainprecision for ARGCONSTALLOCSIZEORZERO Precision markers need to be propagated whenever we have an ARGCONST style argument, as the verifier cannot consider imprecise scalars to be equivalent for the purposes of...
