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: netfilter: ctnetlink: zero expect NAT
 fields when CTA_EXPECT_NAT absent ctnetlink_alloc_expect() allocates expectations from a non-zeroing slab
 cache via nf_ct_expect_alloc(). When CTA_EXPECT_NAT is not present in the netlink message, saved_addr and
 saved_proto are never initialized. Stale data from a previous slab occupant can then be dumped to
 userspace by ctnetlink_exp_dump_expect(), which checks these fields to decide whether to emit
 CTA_EXPECT_NAT. The safe sibling nf_ct_expect_init(), used by the packet path, explicitly zeroes these
 fields. Zero saved_addr, saved_proto and dir in the else branch, guarded by IS_ENABLED(CONFIG_NF_NAT)
 since these fields only exist when NAT is enabled. Confirmed by priming the expect slab with NAT-bearing
 expectations, freeing them, creating a new expectation without CTA_EXPECT_NAT, and observing that the
 ctnetlink dump emits a spurious CTA_EXPECT_NAT containing stale data from the prior allocation.
 (CVE-2026-43026)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
