ErratumUpdated Packages


TOPIC

An update is available for kernel.

This update affects Rocky Linux 8.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed
severity rating, is available for each vulnerability from the CVE list


DESCRIPTION

The kernel packages contain the Linux kernel, the core of any Linux operating
system.



Security Fix(es):



* kernel: ipvlan: out-of-bounds write caused by unclear skb->cb (CVE-2023-3090)



* kernel: UAF in nftables when nft_set_lookup_global triggered after handling
named and anonymous sets in batch requests (CVE-2023-3390)



* kernel: net/sched: cls_fw component can be exploited as result of failure in
tcf_change_indev function (CVE-2023-3776)



* kernel: netfilter: use-after-free due to improper element removal in
nft_pipapo_remove() (CVE-2023-4004)



* kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()
(CVE-2023-35001)



* kernel: cls_flower: out-of-bounds write in fl_set_geneve_opt()
(CVE-2023-35788)



* kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002)



* hw: amd: Cross-Process Information Leak (CVE-2023-20593)
