A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub-component. This flaw allows a local attacker with a user privilege to cause a denial of service. Se ha detectado un fallo de uso de memoria previamente liberada en el archivo fs/ext4/namei.c:dx_insert_block() en el subcomponente del sistema de archivos del kernel de Linux.

CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 10CVE-2022-34918 – Netfilter nft_set_elem_init Heap Overflow Privilege Escalation
https://notcve.org/view.php?id=CVE-2022-34918
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. Se ha detectado un problema en el kernel de Linux versiones hasta 5.18.9. • https://github.com/veritas501/CVE-2022-34918 https://github.com/randorisec/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra25/CVE-2022-34918-LPE-PoC https://github.com/merlinepedra/CVE-2022-34918-LPE-PoC https://github.com/linulinu/CVE-2022-34918 http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html http://packetstormsecurity.com/files/168543/Netfilter-nft_set_elem_init-Heap-Overflow-Privilege-Escalation.html http://www.openwall.com/lists/oss-secur • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-1025: Comparison Using Wrong Factors •
