USN-8887-1 linux, linux-aws, linux-gcp, linux-gke, linux-ibm, linux-oracle, linux-realtime vulnerabilities
It was discovered that some AMD processors did not properly perform Reverse Map Table RMP checks when the IOMMU accessed certain host buffers. A local attacker with hypervisor access could possibly use this to trigger an out-of-bounds condition and compromise the integrity of SEV-SNP guest memory...
USN-8728-2 linux-azure-7.0 vulnerabilities
It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...
USN-8662-2: Linux kernel (FIPS) vulnerabilities
Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - x86 architecture; - Cryptographic API; - InfiniBand drivers; - Media drivers; - STMicroelectronics network drivers;...
CVE-2026-64306
A flaw was found in the Linux kernel's Cryptographic API, specifically within the Counter Mode Deterministic Random Bit Generator CTRDRBG. The drbgctrgenerate function can incorrectly indicate a successful operation even when it has failed. This issue results in the output buffer remaining...
USN-8595-3 linux-aws-6.8, linux-aws-fips vulnerabilities
It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...
USN-8618-1: Linux kernel vulnerabilities
It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...
