kernel: DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c
nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.
A memory corruption flaw was found in the Linux kernel’s Netfilter subsystem in the way a local user uses the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed.

It was discovered that the framebuffer driver on the Linux kernel did not
verify size limits when changing font or screen size, leading to an out-of-
bounds write. A local attacker could use this to cause a denial of service
