CVE-2026-68138 net/sched: serialize qdisc_rtab_list against concurrent get/put

In the Linux kernel, the following vulnerability has been resolved: net/sched: serialize qdiscrtablist against concurrent get/put qdiscgetrtab and qdiscputrtab mutate the process-global singly linked list qdiscrtablist and a plain non-atomic 'int refcnt' with no lock. This was only safe because...

CVE-2026-11742

CVE-2026-11742 describes a use-after-free race in Zephyr’s kernel queue helpers: z_queue_node_peek() can dereference a node after another thread preempts or unlinks it via k_queue_get(), because peek operations weren’t protected by the queue spinlock. A concurrent consumer may free the node and i...

CVE-2026-11742 Use-after-free race in kernel `k_queue_peek_head/tail` due to missing spinlock

The kernel queue helper zqueuenodepeek in kernel/queue.c dereferences a node taken from a queue's dataq list, reading the node's flag byte and, for items enqueued via kqueueallocappend/allocprepend, the data pointer of an internally allocated allocnode struct. The implementations of...

CVE-2026-64501

A flaw was found in the Linux kernel's adsigmadelta driver for analog-to-digital converters ADCs. This vulnerability occurs when the Chip Select CS line, which controls communication with the ADC, remains asserted after a conversion or in an error state. This can prevent other devices on the Seri...

The vulnerability of the loopback_check_format() function in the sound/drivers/aloop.c module of the Linux kernel’s audio subsystem allows a hacker to access protected information or cause service failures.

The vulnerability of the loopbackcheckformat function in the sound/drivers/aloop.c module of the Linux kernel’s audio subsystem is related to the repeated use of previously freed memory due to concurrent access to resources. Exploiting this vulnerability could allow an attacker to gain access to...

CVE-2026-64435

A flaw was found in the Linux kernel's auditing subsystem. Multiple readers could access the auditqueue length qlen concurrently with a writer without proper synchronization, leading to a data race. This race condition could result in inconsistent data reads, potentially causing unpredictable...

CVE-2026-53380

A flaw was found in the Linux kernel's rzv2h-ivc media driver. The driver's buffer list, which is protected by a spinlock, can be concurrently modified because a buffer removal operation listdel is performed outside of the protected section. This concurrent access to the buffer list without prope...

SUSE CVE-2026-63793

In the Linux kernel, the following vulnerability has been resolved: ntfs: serialize volume label accesses Protect vol-volumelabel with a mutex and snaphost the label before copytouser. This prevent a use-after-free when FSIOCSETFSLABEL replaces the vol-volumelabel and FSIOCGETTSLABEL reads it...
