| 2024-05-22 | CVE-2021-47437 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: iio: adis16475: fix deadlock on frequency set With commit 39c024b51b560 ("iio: adis16475: improve sync scale mode handling"), two deadlocks were introduced: 1) The call to 'adis_write_reg_16()' was not changed to it's unlocked version. 2) The lock was not being released on the success path of the function. This change fixes both these issues. | 5.5 |
| 2024-05-22 | CVE-2021-47469 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: Fix deadlock when adding SPI controllers on SPI buses Currently we have a global spi_add_lock which we take when adding new devices so that we can check that we're not trying to reuse a chip select that's already controlled. | 5.5 |
| 2024-05-21 | CVE-2023-52737 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: btrfs: lock the inode in shared mode before starting fiemap Currently fiemap does not take the inode's lock (VFS lock), it only locks a file range in the inode's io tree. | 5.5 |
| 2024-05-21 | CVE-2023-52757 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential deadlock when releasing mids All release_mid() callers seem to hold a reference of @mid so there is no need to call kref_put(&mid->refcount, __release_mid) under @server->mid_lock spinlock. | 7.8 |
| 2024-05-21 | CVE-2021-47349 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mwifiex: bring down link before deleting interface We can deadlock when rmmod'ing the driver or going through firmware reset, because the cfg80211_unregister_wdev() has to bring down the link for us, ... | 5.5 |
| 2024-05-21 | CVE-2021-47359 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cifs: Fix soft lockup during fsstress Below traces are observed during fsstress and system got hung. [ 130.698396] watchdog: BUG: soft lockup - CPU#6 stuck for 26s! | 5.5 |
| 2024-05-21 | CVE-2021-47382 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: s390/qeth: fix deadlock during failing recovery Commit 0b9902c1fcc5 ("s390/qeth: fix deadlock during recovery") removed taking discipline_mutex inside qeth_do_reset(), fixing potential deadlocks. | 4.7 |
| 2024-05-20 | CVE-2024-35953 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix deadlock in context_xa ivpu_device->context_xa is locked both in kernel thread and IRQ context. It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization otherwise the lock could be acquired from a thread and interrupted by an IRQ that locks it for the second time causing the deadlock. This deadlock was reported by lockdep and observed in internal tests. | 5.5 |
| 2024-05-20 | CVE-2024-35968 | Improper Locking vulnerability in Linux Kernel 6.9 In the Linux kernel, the following vulnerability has been resolved: pds_core: Fix pdsc_check_pci_health function to use work thread When the driver notices fw_status == 0xff it tries to perform a PCI reset on itself via pci_reset_function() in the context of the driver's health thread. | 5.5 |
| 2024-05-20 | CVE-2024-35990 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dma: xilinx_dpdma: Fix locking There are several places where either chan->lock or chan->vchan.lock was not held. | 5.5 |
