In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: cancel all works upon hciunregisterdev syzbot is reporting that calling hcireleasedev from hcierrorreset due to hcidevput from hcierrorreset can cause deadlock at destroyworkqueue, for hcierrorreset is called...

CVE-2024-41080 io_uring: fix possible deadlock in io_register_iowq_max_workers()

In the Linux kernel, the following vulnerability has been resolved: iouring: fix possible deadlock in ioregisteriowqmaxworkers The ioregisteriowqmaxworkers function calls ioputsqdata, which acquires the sqd-lock without releasing the uringlock. Similar to the commit 009ad9f0c6ee "iouring: drop...

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-2024-41036

The CVE-2024-41036 vulnerability involves the ks8851 driver in the Linux kernel. When SMP is enabled, functional spinlocks can cause a deadlock between ks8851_start_xmit_spi and ks8851_irq due to contention on the statelock, leading to a soft lockup (high availability impact). The issue occurs in...

kernel: scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()

In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Release hbalock before calling lpfcworkerwakeup lpfcworkerwakeup calls the lpfcworkdone routine, which takes the hbalock. Thus, lpfcworkerwakeup should not be called while holding the hbalock to avoid potential deadlo...
