high Tenable Self-Hosted Container Security Plugin ID 468853

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 TCP_ZEROCOPY_RECEIVE, only rejects values larger than the
 original length. If BPF writes a negative optlen, that value is accepted and propagated back to the TCP
 getsockopt code. It can then be passed to copy_to_sockptr() as a size_t and trigger the hardened usercopy
 bytes > INT_MAX warning. Reject negative ctx.optlen in __cgroup_bpf_run_filter_getsockopt_kern(), matching
 the lower-bound validation already present in the sockptr-based getsockopt hook. (CVE-2026-90157)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
