USN-8945-1: XZ Utils vulnerability

It was discovered that XZ Utils incorrectly handled certain memory allocation failures when reinitializing decoders for specific compressed file formats. An attacker could possibly use this issue to trigger an invalid memory write, resulting in a denial of service or arbitrary code execution...

CVE-2026-90412

A flaw was found in the nvmet component of the Linux kernel. When processing an RMI log page, if memory allocation for the log buffer fails, the system incorrectly reports a successful operation to the host. This can lead to the host believing data was transferred when it was not, potentially...

CVE-2026-98445

A flaw was found in the Linux kernel's XFS file system. A local user could cause a Denial of Service DoS by triggering an online file system repair under low-memory conditions. When a memory allocation failure occurs during repair block reservation, the kernel cannot cleanly recover from the erro...
