CVE-2026-90157
A flaw was found in the Linux kernel. A local attacker could exploit a vulnerability in the BPF Berkeley Packet Filter cgroup getsockopt hook. By providing a negative length value, a malicious BPF program could cause the kernel's memory copy function to process an invalid size. This could lead to...
SUSE CVE-2026-90157
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject negative optlen in cgroup getsockopt hook A cgroup getsockopt BPF program can shrink ctx-optlen after the kernel getsockopt handler has run. The kernel-buffer variant, used by TCPZEROCOPYRECEIVE, only rejects values...

CVE-2026-90157
CVE-2026-90157 affects the Linux kernel BPF cgroup getsockopt hook. A cgroup getsockopt BPF program can shrink ctx->optlen after the kernel getsockopt handler runs. The kernel-buffer variant (used by TCP_ZEROCOPY_RECEIVE ) only rejects values larger than the original length, so a negative optl...
