| 2024-07-29 | CVE-2024-41080 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: io_uring: fix possible deadlock in io_register_iowq_max_workers() The io_register_iowq_max_workers() function calls io_put_sq_data(), which acquires the sqd->lock without releasing the uring_lock. Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock before acquiring sqd->lock"), this can lead to a potential deadlock situation. To resolve this issue, the uring_lock is released before calling io_put_sq_data(), and then it is re-acquired after the function call. This change ensures that the locks are acquired in the correct order, preventing the possibility of a deadlock. | 5.5 |
| 2024-07-23 | CVE-2024-41012 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: filelock: Remove locks reliably when fcntl/close race is detected When fcntl_setlk() races with close(), it removes the created lock with do_lock_file_wait(). However, LSMs can allow the first do_lock_file_wait() that created the lock while denying the second do_lock_file_wait() that tries to remove the lock. Separately, posix_lock_file() could also fail to remove a lock due to GFP_KERNEL allocation failure (when splitting a range in the middle). After the bug has been triggered, use-after-free reads will occur in lock_get_status() when userspace reads /proc/locks. | 6.3 |
| 2024-07-18 | CVE-2024-41011 | Incorrect Calculation vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: don't allow mapping the MMIO HDP page with large pages We don't get the right offset in that case. | 7.8 |
| 2024-07-17 | CVE-2024-41009 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf: Fix overrunning reservations in ringbuf The BPF ring buffer internally is implemented as a power-of-2 sized circular buffer, with two logical and ever-increasing counters: consumer_pos is the consumer counter to show which logical position the consumer consumed the data, and producer_pos which is the producer counter denoting the amount of data reserved by all producers. Each time a record is reserved, the producer that "owns" the record will successfully advance producer counter. | 5.5 |
| 2024-07-16 | CVE-2022-48841 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: fix NULL pointer dereference in ice_update_vsi_tx_ring_stats() It is possible to do NULL pointer dereference in routine that updates Tx ring stats. | 5.5 |
| 2024-07-16 | CVE-2022-48842 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: Fix race condition during interface enslave Commit 5dbbbd01cbba83 ("ice: Avoid RTNL lock when re-creating auxiliary device") changes a process of re-creation of aux device so ice_plug_aux_dev() is called from ice_service_task() context. This unfortunately opens a race window that can result in dead-lock when interface has left LAG and immediately enters LAG again.
