CVE-2026-74593 sched_ext: Take cgroup_lock() first in scx_cgroup_lock()

In the Linux kernel, the following vulnerability has been resolved: schedext: Take cgrouplock first in scxcgrouplock scxcgrouplock write-locks scxcgroupopsrwsem and then takes cgrouplock, which can deadlock through kernfs: scx enable/disable cgroup rmdir cpu.weight write ------------------...

CVE-2026-74593

This CVE affects the Linux kernel 's sched_ext subsystem. The root cause is a lock ordering bug in scx_cgroup_lock(), which acquires scx_cgroup_ops_rwsem (write) before cgroup_lock(). This ordering can create a deadlock through kernfs when concurrent operations on cgroup rmdir and cpu.weight writ...

CVE-2026-74523

A flaw was found in the Linux kernel's qede network driver. When a qede Network Interface Card NIC with VXLAN/GENEVE tunnel ports experiences a transmit TX timeout, a deadlock can occur in the driver's recovery process. This deadlock prevents the system's networking control plane from responding,...

CVE-2026-74463

A flaw was found in the Linux kernel's i2c: jz4780 driver. A severe deadlock can occur between the Common Clock Framework CCF and the I2C adapter lock. This happens when an I2C-controlled clock generator client is registered or modified, and a concurrent I2C transfer attempts to acquire a lock...

CVE-2026-74572

A flaw was found in the Linux kernel's btrfs zoned filesystem. A local user could trigger a deadlock when metadata writeback and transaction commit operations occur simultaneously. This deadlock causes the system to hang, leading to a Denial of Service DoS...

CVE-2026-74574

A flaw was found in the Linux kernel's dmaengine IDXD subsystem. A race condition during file-device setup failure cleanup in the idxdcdevopen function could lead to a deadlock, causing a denial of service. Furthermore, incorrect cleanup paths could result in operations on a freed memory context,...

CVE-2026-74526

A flaw was found in the Linux kernel's mpi3mr SCSI driver. When the mpi3mrfaultueventemit function is called from fault watchdog or reset paths, memory allocation requests can trigger a reclaim process. This reclaim process may then wait on host I/O that is already blocked, leading to a system...

CVE-2026-74535

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability arises from a race condition where the isosocktimeout function can execute concurrently with isoconndel, leading to a Use-After-Free UAF condition. A UAF vulnerability allows an attacker to potentially execute...

CVE-2026-74337

A flaw was found in the Linux kernel, specifically within the BPF Berkeley Packet Filter subsystem. This vulnerability allows NMI Non-Maskable Interrupt and tracepoint BPF programs to re-enter certain internal locks, known as LRU Least Recently Used locks, while they are already held. This re-ent...

CVE-2026-74318

A flaw was found in the Linux kernel's btrfs filesystem. A local user could trigger a deadlock when cloning an inline extent with the flushoncommit mount option, specifically when the destination offset is greater than zero. This issue occurs due to a missing isize update during the copy operatio...

CVE-2026-74354

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A local attacker could exploit a locking issue within the zappages function. This vulnerability arises because zapvmarange requires a specific memory map lock mmaplock that, when acquired under certain conditions, can le...

CVE-2026-74437

A flaw was found in the Linux kernel's uvcvideo module, which manages USB Video Class UVC devices. When a UVC camera with asynchronous control is in use, a specific sequence of operations can lead to a deadlock within the kernel. This vulnerability could allow a local attacker to cause a...

CVE-2026-74319

A flaw was found in the btrfs zoned filesystem within the Linux kernel. When performing data relocation, the system can enter a deadlock state. This happens because the relocation process waits for a space reservation ticket that cannot be fulfilled, as the relocation itself is the operation...

CVE-2026-74375

A flaw was found in the Linux kernel's RAID1 and RAID10 subsystems. When handling read errors, a specific sequence of operations involving cloned I/O requests and array suspension can lead to a deadlock. This can cause the system to become unresponsive, resulting in a Denial of Service DoS...
