Deadlock in x86 HVM standard VGA handling

ISSUE DESCRIPTION The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the virtual VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a...

kernel: smb: client: fix potential deadlock when releasing mids

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential deadlock when releasing mids All releasemid callers seem to hold a reference of @mid so there is no need to call krefput&mid-refcount, releasemid under @server-midlock spinlock. If they don't, then an...

kernel: dpll: fix possible deadlock during netlink dump operation

A vulnerability was found in the Linux kernel, where an ABBA deadlock condition may be created if multiple CPUs attempt a DPLL netlink dump operation simultaneously. This deadlock could lead to performance issues...

kernel: net/sched: act_mirred: use the backlog for mirred ingress

A potential deadlock flaw was found in net/sched/actmirred.c in the Linux kernel. This may lead to compromised Availability...

kernel: dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape

In the Linux kernel, the following vulnerability has been resolved: dm-raid456, md/raid456: fix a deadlock for dm-raid456 while io concurrent with reshape For raid456, if reshape is still in progress, then IO across reshape position will wait for reshape to make progress. However, for dm-raid, in...

kernel: net/sched: Fix mirred deadlock on device recursion

In the Linux kernel, the following vulnerability has been resolved: net/sched: Fix mirred deadlock on device recursion The Linux kernel CVE team has assigned CVE-2024-27010 to this issue. Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024050148-CVE-2024-27010-5a68@gregkh/T...

kernel: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

A deadlock flaw was found in the Linux kernel’s pinctrl subsystem. This flaw allows a local user to crash the system...

kernel: serial: imx: Introduce timeout when waiting on transmitter empty

A vulnerability was found in the Linux kernel's imx serial driver, where the system could experience DoS while waiting for the transmitter to become empty, without a timeout mechanism, the code risks entering a deadlock situation if the USR2TXDC signal is not set...

kernel: drm/amdgpu: fix deadlock while reading mqd from debugfs

A flaw was found in the drm/amdgpu subsystem in the Linux kernel, involving a deadlock occurring when reading the Memory Queue Descriptor MQD from debugfs. This issue could cause the system to hang during debug operations...

kernel: Bluetooth: hci_core: cancel all works upon hci_unregister_dev()

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...

kernel: nouveau: offload fence uevents work to workqueue

In the Linux kernel, the following vulnerability has been resolved: nouveau: offload fence uevents work to workqueue This should break the deadlock between the fctx lock and the irq lock. This offloads the processing off the work from the irq into a workqueue...

kernel: PCI/ASPM: Fix deadlock when enabling ASPM

A flaw was found in the Linux kernel, where a deadlock scenario was triggered when enabling Active State Power Management ASPM during the probe of Qualcomm PCIe controllers. This deadlock was identified by lockdep and stemmed from a recursive locking scenario. This issue occurred when a task...

kernel: wifi: rt2x00: restart beacon queue when hardware reset

A flaw was found in the Linux kernel. When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in the hardware interface. However, mac80211 will not automatically stop the queue. If the beacon queue is not manually stopped, it will be deadlocked and unable to...

kernel: mm: use memalloc_nofs_save() in page_cache_ra_order()

In the Linux kernel, the following vulnerability has been resolved: mm: use memallocnofssave in pagecacheraorder See commit f2c817bed58d "mm: use memallocnofssave in readahead path", ensure that pagecacheraorder do not attempt to reclaim file-backed pages too, or it leads to a deadlock, found iss...

A flaw was found in the Linux kernel, where a deadlock can occur between bdlinkdiskholder and partition scan...

kernel: i2c: lpi2c: Avoid calling clk_get_rate during transfer

A vulnerability was found in the lpi2c driver in the Linux kernel's i2c subsystem, where the clkgetrate function is called during data transfers, which can lead to a deadlock situation when an audio codec attempts to access the i2c bus while holding the clock mutex, resulting in a denial of servi...
