https://notcve.org/view.php?id=CVE-2022-36946
27 Jul 2022 — 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. La función nfqnl_mangle en el archivo net/netfilter/nfnetlink_queue.c en el kernel de Linux versiones hasta 5.18.14, permite a atacantes remotos causar una denegación de servicio (pánico) porque, en el caso de un veredicto nf_queue con ... • https://github.com/Pwnzer0tt1/CVE-2022-36946 •

CVE-2022-2991 – Linux Kernel LightNVM Subsystem Heap-based Overflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2991
11 Jul 2022 — A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability. Se encontró un desbordamiento de bú... • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
