Description
linux-oem-6.1 vulnerabilities Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32233) Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu Linux kernel contained a race condition when handling inode locking in some situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2023-2612)
