Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking, allowing a privileged attacker to remove address ranges from memory. This creates an opportunity to circumvent SecureBoot protections after proper analysis of grub’s memory layout. The...

In the Linux kernel, the following vulnerability has been resolved: MIPS: mm: Fix out-of-bounds write in maarreswalk maarreswalk uses wi-numcfg as the index into the fixed-size wi-cfg array, but checks whether the array is full only after it has filled the selected entry. If walksystemramrange...

CVE-2026-80627

This Linux kernel vulnerability affects the MIPS memory management subsystem. The function maar_res_walk() uses wi->num_cfg as an index into a fixed-size wi->cfg array but checks whether the array is full only after writing the entry. If walk_system_ram_range() reports more than 16 memory r...
