Threats tagged 'usn-8726-2'

Multiple security vulnerabilities were discovered in the Linux kernel affecting a wide range of subsystems and architectures, including ARM64, ARM32, RISC-V, x86, and many drivers and filesystems. One notable issue (CVE-2025-10263) involves some ARM processors completing a broadcast TLB invalidation before memory writes through the invalidated translation are globally observed, potentially allowing local attackers to write to memory after permissions were revoked, bypassing memory protections or escalating privileges. These flaws could be exploited to compromise system security. A patch fixing these vulnerabilities is available.
