Echo: linux: security update to 6.12.9-1

medium Tenable Cloud Security Plugin ID 457337

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: 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 the change
in bpf_helper_changes_pkt_data() automatically makes use of check_cfg() logic that computes
'changes_pkt_data' effect for global sub-programs, such that the following program could be rejected: int
tail_call(struct __sk_buff *sk) { bpf_tail_call_static(sk, &jmp_table, 0); return 0; } SEC("tc") int
not_safe(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; ... make p valid ... tail_call(sk); *p =
42; /* this is unsafe */ ... } The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that can
invalidate packet pointers. Otherwise, it can't be freplaced with tailcall_freplace.c:entry_freplace()
that does a tail call. (CVE-2024-58237)

Solution

Update the linux library and its related packages to version 6.12.9-1 or later.
