Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Do not override the return value of subprog The verifier test "calls: div by 0 in subprog" triggers a panic at the ld.bu instruction. The ld.bu instruction attempts to load a byte from the memory address returned ...

UBUNTU-CVE-2022-50168

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: fix freeing of not-finalized bpfprogpack syzbot reported a few issues with bpfprogpack 1, 2. This only happens with multiple subprogs. In jitsubprogs, we first call bpfintjitcompile on each sub program. And then, we cal...

UBUNTU-CVE-2024-58237

In the Linux kernel, the following vulnerability has been resolved: bpf: consider that tail calls invalidate packet pointers Tail-called programs could execute any of the helpers that invalidate packet pointers. Hence, conservatively assume that each tail call invalidates packet pointers. Making...

CVE-2025-22048

Summary of CVE-2025-22048 (Linux kernel LoongArch BPF issue) : The problem was triggered by sign-extending the BPF return value. After commit 73c359d1d356, a5 (BPF return value) was sign-extended to a0, and for native calls the a0 value was propagated back to a5. For bpf2bpf calls this propagatio...
