CVE-2024-45024

The CVE-2024-45024 issue in the Linux kernel concerns page-table locking around hugetlb folios during GUP page-walking. The fix implements a technique to use a PTE lock pointer (ptep_lockptr) so the PTE page-table lock can be acquired consistently with core-mm locking, addressing locking mismatch...

Unspecified vulnerability in Linux kernel (CNVD-2024-39520)

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...

Key safe security, or the lack of it

A few years back we put a key safe into our office. Previously, we had used a very simple locked cabinet to ensure keys were returned, as before that, keys kept being accidentally taken home. There’s no data of significance kept at the office. Everything is hosted elsewhere, but we could do witho...
