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: af_unix: Fix garbage collector racing
against connect() Garbage collector does not take into account the risk of embryo getting enqueued during
the garbage collection. If such embryo has a peer that carries SCM_RIGHTS, two consecutive passes of
scan_children() may see a different set of children. Leading to an incorrectly elevated inflight count,
and then a dangling pointer within the gc_inflight_list. sockets are AF_UNIX/SOCK_STREAM S is an
unconnected socket L is a listening in-flight socket bound to addr, not in fdtable V's fd will be passed
via sendmsg(), gets inflight count bumped connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- ----------- NS = unix_create1() skb1 = sock_wmalloc(NS) L =
unix_find_other(addr) unix_state_lock(L) unix_peer(S) = NS // V count=1 inflight=0 NS = unix_peer(S) skb2
= sock_alloc() skb_queue_tail(NS, skb2[V]) // V became in-flight // V count=2 inflight=1 close(V) // V
count=1 inflight=1 // GC candidate condition met for u in gc_inflight_list: if (total_refs ==
inflight_refs) add u to gc_candidates // gc_candidates={L, V} for u in gc_candidates: scan_children(u,
dec_inflight) // embryo (skb1) was not // reachable from L yet, so V's // inflight remains unchanged
__skb_queue_tail(L, skb1) unix_state_unlock(L) for u in gc_candidates: if (u.inflight) scan_children(u,
inc_inflight_move_tail) // V count=1 inflight=2 (!) If there is a GC-candidate listening socket,
lock/unlock its state. This makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if there is another embryo coming,
it can not possibly carry SCM_RIGHTS. At this point, unix_inflight() can not happen because unix_gc_lock
is already taken. Inflight graph remains unaffected. (CVE-2024-26923)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.1.61 or later.
