It was 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. Lonial Con discovered that the netfilter subsystem in the Linux kernel contained a memory leak when handling certain element flush operations. A local attacker could use this to expose sensitive information (kernel memory). Various other issues were also addressed.
