CVE-2026-98738

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition occurs when the Security Manager Protocol SMP accesses remote Out-of-Band OOB pairing data without proper locking while the data is concurrently being removed. A local attacker can exploit this flaw to trigger a...

CVE-2026-98733

A flaw was found in the Linux kernel's Bluetooth subsystem. Inadequate synchronization when handling fragmented isochronous ISO data packets allows a race condition between packet queueing and transmission operations. A local user could exploit this flaw to trigger a use-after-free condition,...

CVE-2026-98737

A flaw was found in the Linux kernel's Bluetooth subsystem. This flaw allows a local user to cause a Denial of Service DoS or potentially escalate privileges due to a use-after-free condition. The issue arises from a race condition where synchronous command routines access inquiry cache entries...

CVE-2026-98708

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local user could exploit this flaw to cause a Denial of Service DoS or system instability. During in-place channel context replacement, an old channel context can be freed prematurely while still referenced by its replacement...

CVE-2026-98696

A flaw was found in the Linux kernel's USB serial subsystem. A local user with administrative privileges could exploit this flaw to cause a Denial of Service DoS or memory corruption. During the unloading of a USB serial driver module, drivers are deregistered in an incorrect sequence, allowing...

CVE-2026-98650

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for the s390 architecture. A race condition occurs when storage key management functions process large memory pages that are simultaneously split by another thread. A local user could exploit this timing issue durin...

CVE-2026-98639

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for the RISC-V architecture. During nested virtualization acceleration, control flags are written before the target page parameters are properly committed to shared memory. Consequently, the supervisor interface or...

CVE-2026-98742

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer subsystem. A local user could exploit a race condition caused by missing locking during compatibility ioctl input/output control operations. By sending concurrent port creation requests, an attacker can corrup...

CVE-2026-98750

A flaw was found in the Linux kernel's TTY terminal subsystem. A race condition occurs when closing a terminal device while the device number is simultaneously re-registered by a driver that does not guarantee minor number exclusivity. A local attacker could exploit this timing window to trigger ...

CVE-2026-98861

A flaw was found in the Linux kernel's function probe fprobe tracing mechanism. When handlers execute during inactive Read-Copy Update RCU, a kernel synchronization mechanism states, unregistration routines fail to wait for active handlers to complete before freeing memory. A privileged local...

CVE-2026-98859

A flaw was found in the Linux kernel's Human Interface Device HID multitouch driver. When a multitouch device is disconnected or removed, the driver fails to prevent the release timer from being rescheduled by incoming input reports. Once the driver deallocates the device data, the timer callback...

CVE-2026-98840

A flaw was found in the Linux kernel's virtual console screen driver. A race condition between virtual console write operations and console deallocation can cause the kernel to access previously freed memory, resulting in a use-after-free vulnerability. A local user could exploit this flaw to cau...

CVE-2026-98762

A flaw was found in the Linux kernel's USB DWC2 driver. A race condition during host controller teardown or initialization failure allows the wakeup timer to execute after host resources have been released. A local user could exploit this use-after-free vulnerability to cause a Denial of Service...

CVE-2026-98776

A flaw was found in the Linux kernel's Android Binder filesystem binderfs. A local user can exploit a race condition during concurrent device creation and deletion to trigger a use-after-free UAF condition, which occurs when freed memory is written to while being re-registered. This issue may all...

CVE-2026-98830

A flaw was found in the Linux kernel's Silicon Labs WFx Wi-Fi driver. The driver fails to validate the length of firmware responses during Management Information Base MIB queries before copying the data into memory buffers. A compromised or malicious wireless device could supply an oversized...

CVE-2026-98800

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When a BPF program attached to a trampoline is detached, the kernel may release the program's memory prematurely before preempted tasks have safely completed execution. A local user can exploit this race condition to...

SUSE CVE-2024-50073

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: Fix use-after-free in gsmcleanupmux BUG: KASAN: slab-use-after-free in gsmcleanupmux+0x77b/0x7b0 drivers/tty/ngsm.c:3160 ngsm Read of size 8 at addr ffff88815fe99c00 by task poc/3379 CPU: 0 UID: 0 PID: 3379 Comm: poc N...
