USN-8048-1: Linux kernel (OEM) 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: - ARM64 architecture; - MIPS architecture; - Nios II architecture; - PA-RISC architecture; - RISC-V architecture; -...

UBUNTU-CVE-2025-40245

In the Linux kernel, the following vulnerability has been resolved: nios2: ensure that memblock.currentlimit is set when setting pfn limits On nios2, with CONFIGFLATMEM set, the kernel relies on memblockgetcurrentlimit to determine the limits of memmap, in particular for maxlowpfn. Unfortunately,...
