high Tenable Self-Hosted Container Security Plugin ID 467338

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, sockmap: reject overflowing copy
 + len in bpf_msg_push_data() When the scatterlist ring is full or nearly full, bpf_msg_push_data() enters
 a copy fallback path and computes copy + len for the page allocation size. Since len comes from BPF with
 arg3_type = ARG_ANYTHING and both are u32, a crafted len can wrap the sum to a small value, causing an
 undersized allocation followed by an out-of-bounds memcpy. BUG: unable to handle page fault for address:
 ffffed104089a402 Oops: Oops: 0000 [#1] SMP KASAN NOPTI Call Trace: __asan_memcpy (mm/kasan/shadow.c:105)
 bpf_msg_push_data (net/core/filter.c:2852 net/core/filter.c:2788) bpf_prog_9ed8b5711920a7d7+0x2e/0x36
 sk_psock_msg_verdict (net/core/skmsg.c:934) tcp_bpf_sendmsg (net/ipv4/tcp_bpf.c:421
 net/ipv4/tcp_bpf.c:584) __sys_sendto (net/socket.c:2206) do_syscall_64 (arch/x86/entry/syscall_64.c:94)
 entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:130) Add an overflow check before the
 allocation. (CVE-2026-64548)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.43 or later.
