Summary
linux-oem-6.1 vulnerabilities
Details

Ruihan Li discovered that the memory management subsystem in the Linux kernel contained a race condition when accessing VMAs in certain conditions, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3269)

Querijn Voet discovered that a race condition existed in the io_uring subsystem in the Linux kernel, 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-2023-3389)
