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: tcp_bpf: Fix the sk_mem_uncharge logic
in tcp_bpf_sendmsg The current sk memory accounting logic in __SK_REDIRECT is pre-uncharging tosend bytes,
which is either msg->sg.size or a smaller value apply_bytes. Potential problems with this strategy are as
follows: - If the actual sent bytes are smaller than tosend, we need to charge some bytes back, as in line
487, which is okay but seems not clean. - When tosend is set to apply_bytes, as in line 417, and (ret <
0), we may miss uncharging (msg->sg.size - apply_bytes) bytes. [...] 415 tosend = msg->sg.size; 416 if
(psock->apply_bytes && psock->apply_bytes < tosend) 417 tosend = psock->apply_bytes; [...] 443
sk_msg_return(sk, msg, tosend); 444 release_sock(sk); 446 origsize = msg->sg.size; 447 ret =
tcp_bpf_sendmsg_redir(sk_redir, redir_ingress, 448 msg, tosend, flags); 449 sent = origsize -
msg->sg.size; [...] 454 lock_sock(sk); 455 if (unlikely(ret < 0)) { 456 int free =
sk_msg_free_nocharge(sk, msg); 458 if (!cork) 459 *copied -= free; 460 } [...] 487 if (eval ==
__SK_REDIRECT) 488 sk_mem_charge(sk, tosend - sent); [...] When running the selftest
test_txmsg_redir_wait_sndmem with txmsg_apply, the following warning will be reported: ------------[ cut

__SK_REDIRECT, a more concise way is delaying the uncharging after sent bytes are finalized, and uncharge
this value. When (ret < 0), we shall invoke sk_msg_free. Same thing happens in case __SK_DROP, when tosend
is set to apply_bytes, we may miss uncharging (msg->sg.size - apply_bytes) bytes. The same warning will be
reported in selftest. [...] 468 case __SK_DROP: 469 default: 470 sk_msg_free_partial(sk, msg, tosend); 471
sk_msg_apply_bytes(psock, tosend); 472 *copied -= (tosend + delta); 473 return -EACCES; [...] So instead
of sk_msg_free_partial we can do sk_msg_free here. (CVE-2024-56633)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 19165.0.0 or later.
