USN-8760-1: Linux kernel (NVIDIA) vulnerabilities
Canonical issues USN-8760-1 patching multiple Linux kernel (NVIDIA) vulnerabilities across numerous subsystems and CPU architectures.
Canonical published USN-8760-1 to correct several Linux kernel (NVIDIA) vulnerabilities that an attacker could possibly use to compromise the system. The update fixes flaws spanning UAPI, the kernel build system, ARM32, ARM64, RISC-V, S390, and x86 architectures. Patched subsystems also include the block layer, cryptographic API, Compute Acceleration Framework, Intel NPU driver, ACPI and Bluetooth drivers, and the hardware random number generator core.

USN-8733-1: Gzip vulnerabilities
Ubuntu issued USN-8733-1 fixing two Gzip flaws: insecure gzexe temp files allowing file overwrites, and a crafted-file DoS/info exposure bug.
USN-8733-1 updates Gzip in Ubuntu to fix CVE-2026-41991, where the gzexe utility created temporary files insecurely when mktemp was unavailable, letting a local attacker overwrite arbitrary files. It also fixes CVE-2026-41992, incorrect handling of certain compressed files that could expose sensitive information or crash Gzip in a denial of service. Both issues have local impact and are addressed via updated Ubuntu packages.
