CVE-2022-48887: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Remove rcu locks from user resources User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two...

CVE-2024-43834

In the Linux kernel, the following vulnerability has been resolved: xdp: fix invalid wait context of pagepooldestroy If the driver uses a page pool, it creates a page pool with pagepoolcreate. The reference count of page pool is 1 as default. A page pool will be destroyed only when a reference...

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...

CVE-2024-41952 Zitadel has an "Ignoring unknown usernames" vulnerability

Zitadel is an open source identity management system. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report...

CVE-2024-41080

CVE-2024-41080 concerns the Linux kernel and describes a deadlock risk in io_uring when locking order is not respected in io_register_iowq_max_workers. The root cause is that io_put_sq_data() can be called while uring_lock is held, risking deadlock with sqd->lock. The documented fix releases u...

CVE-2024-41012

In the Linux kernel, CVE-2024-41012 pertains to a fcntl/close race in file locking where an LSM could allow the first do_lock_file_wait() to acquire a lock while denying the second removal, and POSIX lock removal could fail due to GFP_KERNEL allocation during range splitting. The issue can lead t...

kernel: can: j1939: prevent deadlock by changing j1939_socks_lock to rwlock

A vulnerability was found in the Linux kernel's Controller Area Network CAN protocol, within the J1939 protocol implementation. This issue occurs due to a potential deadlock caused by a race condition involving three locks: j1939sockslock, activesessionlistlock, and sksessionqueuelock. This issue...
