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: nf_conntrack_irc: fix
parse_dcc() off-by-one OOB read parse_dcc() treats data_end as an inclusive end pointer, but its only
caller passes data_limit = ib_ptr + datalen, which points one past the last valid byte. The newline search
loop iterates while tmp <= data_end, so when no newline is present, *tmp is read at tmp == data_end, one
byte beyond the region filled by skb_header_pointer(). irc_buffer is kmalloc'd as MAX_SEARCH_SIZE + 1
bytes and datalen is capped at MAX_SEARCH_SIZE, so the stray read does not fault. The byte is
uninitialized or stale; if it contains an ASCII digit, simple_strtoul will consume it and produce a wrong
DCC IP or port in the conntrack expectation. The extra allocation byte is also a fragile guard: if the cap
or allocation size changes, this becomes a real out-of-bounds read. Change the loop and its post-loop
check to use strict less-than, consistent with the caller's exclusive-end convention. Update the function
comment accordingly. (CVE-2026-80603)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.3 or later.
