CVE-2026-80876

CVE-2026-80876 affects the Linux kernel ring-buffer subsystem on architectures where RB_FORCE_8BYTE_ALIGNMENT is true (observed on riscv64 with CONFIG_HAVE_64BIT_ALIGNED_ACCESS=y). The root cause is a mismatch in length calculation: rb_calculate_event_length() unconditionally reserves sizeof(even...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: “hungtask”: fixed warnings caused by unaligned lock pointers. The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned, so that their lower bits can be used for type encoding. However, as reported by...
