    <Note Title="Topic" Type="Summary" Ordinal="1" xml:lang="en">Security update for the Linux Kernel (Live Patch 2 for SLE 15 SP4)</Note>
    <Note Title="Details" Type="General" Ordinal="2" xml:lang="en">This update for the Linux Kernel 5.14.21-150400_24_16 fixes several issues.

The following security issues were fixed:
- CVE-2020-36516: Fixed an off-path attack via mixed IPID assignment method with the hash-based IPID assignment policy to inject data into a victim's TCP session or terminate that session (bsc#1196867).
- CVE-2021-39698: Fixed possible memory corruption in aio_poll_complete_work of aio.c, that could have led to local escalation of privilege with no additional execution privileges needed (bsc#1196959).
- CVE-2022-36946: Fixed a remote denial of service attack inside nfqnl_mangle in net/netfilter/nfnetlink_queue.c, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative length (bsc#1201941).
