https://notcve.org/view.php?id=CVE-2022-2586
10 Aug 2022 — It was discovered that a nft object or expression could reference a nft set on a different nft table, leading to a use-after-free once that table was deleted. Se descubrió que un objeto o expresión nft podía hacer referencia a un conjunto nft en una tabla nft diferente, lo que generaba un use-after-free una vez que se eliminaba esa tabla. A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker t... • https://github.com/aels/CVE-2022-2586-LPE • CWE-416: Use After Free •

29 Jul 2022 — The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. El kernel de Linux versiones anteriores a 5.18.13, carece de una determinada operación de borrado para el símbolo de inicio de bloque (.bss). Esto permite a usuarios del SO huésped Xen PV causar una denegación de servicio o conseguir privilegios • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.18.13 •

28 Jul 2022 — A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.
