CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 2CVE-2022-2586 – Linux Kernel Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2022-2586
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 to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. • https://github.com/aels/CVE-2022-2586-LPE https://github.com/sniper404ghostxploit/CVE-2022-2586 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2586 https://lore.kernel.org/netfilter-devel/20220809170148.164591-1-cascardo@canonical.com/T/#t https://ubuntu.com/security/notices/USN-5557-1 https://ubuntu.com/security/notices/USN-5560-1 https://ubuntu.com/security/notices/USN-5560-2 https://ubuntu.com/security/notices/USN-5562-1 https://ubuntu.com/security/notices&# • CWE-416: Use After Free •

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 https://github.com/sickcodes/security/blob/master/advisories/SICK-2022-128.md https://github.com/torvalds/linux/commit/74a0032b8524ee2bd4443128c0bf9775928680b0 https://github.com/torvalds/linux/commit/96e8fc5818686d4a1591bb6907e7fdb64ef29884 https://security.netapp.com/advisory/ntap-20220901-0003 https://sick.codes/sick-2022-128 •

https://notcve.org/view.php?id=CVE-2022-36879
An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.14. la función xfrm_expand_policies en el archivo net/xfrm/xfrm_policy.c puede causar que un refcount sea descartado dos veces A flaw was found in the Linux kernel’s IP framework for transforming packets (XFRM subsystem). An error while resolving policies in xfrm_bundle_lookup causes the refcount to drop twice, leading to a possible crash and a denial of service. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=f85daf0e725358be78dfd208dea5fd665d8cb901 https://github.com/torvalds/linux/commit/f85daf0e725358be78dfd208dea5fd665d8cb901 https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security.netapp.com/advisory/ntap-20220901-0007 https://www.debian.org/security/2022/dsa-5207 https://access.redhat.com/security/cve/CVE-2022-36879 https://bugzilla.r • CWE-911: Improper Update of Reference Count •
