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_h323: Add
 protection for bmp length out of range UBSAN load reports an exception of BRK#5515 SHIFT_ISSUE:Bitwise
 shifts that are out of bounds for their data type. vmlinux get_bitmap(b=75) + 712
 <net/netfilter/nf_conntrack_h323_asn1.c:0> vmlinux decode_seq(bs=0xFFFFFFD008037000, f=0xFFFFFFD008037018,
 level=134443100) + 1956 <net/netfilter/nf_conntrack_h323_asn1.c:592> vmlinux
 decode_choice(base=0xFFFFFFD0080370F0, level=23843636) + 1216 <net/netfilter/nf_conntrack_h323_asn1.c:814>
 vmlinux decode_seq(f=0xFFFFFFD0080371A8, level=134443500) + 812
 <net/netfilter/nf_conntrack_h323_asn1.c:576> vmlinux decode_choice(base=0xFFFFFFD008037280, level=0) +
 1216 <net/netfilter/nf_conntrack_h323_asn1.c:814> vmlinux DecodeRasMessage() + 304
 <net/netfilter/nf_conntrack_h323_asn1.c:833> vmlinux ras_help() + 684
 <net/netfilter/nf_conntrack_h323_main.c:1728> vmlinux nf_confirm() + 188
 <net/netfilter/nf_conntrack_proto.c:137> Due to abnormal data in skb->data, the extension bitmap length
 exceeds 32 when decoding ras message then uses the length to make a shift operation. It will change into
 negative after several loop. UBSAN load could detect a negative shift as an undefined behaviour and
 reports exception. So we add the protection to avoid the length exceeding 32. Or else it will return out
 of range error and stop decoding. (CVE-2024-26851)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.85.5 or later.
