NewCVE-2026-98801 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 6.12.113, 6.18.56, 7.2.10 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow due to improper validation of the value provided to the SO_RESERVE_MEM socket option in the sk_setsockopt process. An attacker can cause memory corruption and potentially execute arbitrary code or crash the system by supplying excessively large values to the socket option, leading to integer overflow and buffer overflow in memory allocation.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
