Descriptions
A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges.
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 or execute arbitrary code. 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 or possibly execute arbitrary code.
