Multiple security vulnerabilities were discovered in the Linux kernel, including a critical issue affecting some Arm processors where a broadcast TLB invalidation could complete before memory writes were globally observed. This flaw could allow a local attacker to write to memory after permissions were revoked, potentially bypassing memory protections or escalating privileges. The update addresses these issues across various subsystems such as ARM64 architecture, InfiniBand, network drivers, file systems, and networking protocols. A patch is available and should be applied to mitigate these vulnerabilities.
