Threats tagged 'usn-8817-1'

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. Additional vulnerabilities affect various kernel subsystems such as InfiniBand drivers, network drivers, TCM subsystem, and several networking protocols. These issues have been addressed in updated Linux kernel versions.
