CVSS: 8.2EPSS: 0%CPEs: 1EXPL: 0CVE-2022-2991 – Linux Kernel LightNVM Subsystem Heap-based Overflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2991
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 búfer en la región heap de la memoria en el subsistema LightNVM del kernel de Linux. • https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8 https://www.zerodayinitiative.com/advisories/ZDI-22-960 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
