Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: bpf: It is necessary to preserve the id of the register in the synclinked regs function. The synclinked regs function copies the id of knownreg to reg when propagating the bounds of knownreg to reg, using the offset of knownreg...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix insufficient bounds propagation from adjustscalarminmaxvals Kuee reported a corner case where the tnum becomes constant after the call to regboundoffset, but the bounds of the register are not correct. In particular, its...

CVE-2026-45933

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The synclinkedregs function fails to preserve the register ID during bounds propagation, which can lead to incorrect register state. This issue may allow a local attacker to trigger a 'division by zero' error, resulting i...

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

UBUNTU-CVE-2026-45933

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

CVE-2026-45933

CVE-2026-45933 affects the Linux kernel BPF verifier. The root cause is that sync_linked_regs() failed to preserve the register ID during bounds propagation, so when known_reg bounds were propagated to reg, reg retained an old/new id mismatch. This can cause incorrect bound propagation across lin...

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

PT-2026-43800

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF verifier where the sync linked regs function incorrectly copies the ID of a known register to another register when propagating bounds. Specifically, if a...

CVE-2026-43070

In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPFEND value tracking When a register undergoes a BPFEND byte swap operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register e.g., after an r1...

CVE-2022-49658

CVE-2022-49658 concerns the Linux kernel’s BPF bounds propagation. The issue stems from insufficient propagation of tnum min/max bounds into register bounds during operations like adjust_scalar_min_max_vals, allowing a register that becomes a constant-like value to leak pointers when it is later ...
