PT-2026-79629

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A deadlock can occur in the netfilter nf conntrack component when TCP and SCTP conntrack paths emit invalid-packet logs while the ct-lock is still held. If invalid logging is routed to...

PT-2026-79691

In the Linux kernel, the following vulnerability has been resolved: rqspinlock: Reset tail when preserving queue on deadlock Currently, the destruction of the waiter queue is suppressed for rqspinlock in cases where a deadlock is detected. Deadlock checks happen relatively frequently on entry for...

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,...

SUSE CVE-2026-72186

In the Linux kernel, the following vulnerability has been resolved: ntfs: make system files immutable to prevent corruption When a system file such as $Bitmap is exposed via showsysfiles and written from userspace, the volume is corrupted and, because the cluster allocator scans $Bitmap through t...

SUSE CVE-2026-72203

In the Linux kernel, the following vulnerability has been resolved: ntfs: skip extent mft records in writeback to prevent deadlock This patch fixes the ABBA deadlock between extentlock and extent mreclock triggered by xfstests generic/113, that occurs since the commit 6994acf33bae "ntfs: use base...

Unity Linux 20.1050e Security Update: kernel (UTSA-2026-102062)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-102062 advisory. In the Linux kernel, the following vulnerability has been resolved: drm/radeon: delete radeonfenceprocess in issignaled, no deadlock Delete the attempt to progress t...

ROS-20260821-73-0052

The vulnerabilities of the freezerapplystate and freezerchangestate functions in the kernel/cgroup/legacyfreezer.c module of the Linux operating system are related to the occurrence of mutual locking. Exploiting these vulnerabilities can allow attackers to compromise the confidentiality, integrit...

CVE-2026-74374

A flaw was found in the Linux kernel's md/raid1 and md/raid10 modules. An issue in detecting the error path when using mdclonedbio can lead to incorrect memory allocation flags. This misallocation can result in a system deadlock under memory pressure, causing a denial of service...

CVE-2026-74307

A flaw was found in the Linux kernel's ext4 filesystem. A local attacker can trigger a deadlock by performing an EXT4IOCMOVEEXT ioctl operation with a donor file from a different filesystem during a concurrent freeze operation. This late validation creates a circular lock dependency, leading to a...

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...
