kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete
A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...
USN-8620-3: Linux kernel (Intel IoTG) vulnerabilities
Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...
SUSE CVE-2022-4994
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: wean fast IN from emulatorpioin Use emulatorpioin directly for fast PIO instead of bouncing through emulatorpioin now that emulatorpioin fills "val" when handling in-kernel PIO. vcpu-arch.pio.count is guaranteed to be...
The vulnerability of the drm_compat_ioctl() function in the drivers/gpu/drm/drm_ioc32.c file of the Direct Rendering Infrastructure (DRI) driver for the Linux operating system allows a hacker to compromise the confidentiality, integrity, and accessibility of protected information.
The vulnerability of the drmcompatioctl function in the drivers/gpu/drm/drmioc32.c file of the Direct Rendering Infrastructure DRI driver in the Linux kernel relates to the disclosure of confidential information. Exploiting this vulnerability could allow an attacker to compromise the...

In the Linux kernel, the following vulnerability has been resolved: esp: fix page frag reference leak on skbtosgvec failure In espoutputtail, when esp-inplace is false, the old skb page frags are replaced with a new page from the xfrm pagefrag cache. The source scatterlist sg is built from the ol...
SUSE CVE-2026-64556
In the Linux kernel, the following vulnerability has been resolved: perf/core: Detach event groups during removeonexec perfeventremoveonexec removes events by calling perfeventexitevent. For top-level events, this removes the event from the context with DETACHEXIT only. This can leave inconsisten...

CVE-2026-43499-...
CVE-2026-64335
A flaw was found in the Linux kernel's USB serial digiacceleport driver. This vulnerability occurs when a port is closed while it is in a throttled state, preventing the read Urban Request Block URB from being resubmitted. As a result, the affected port will cease to receive any further data,...
CVE-2026-64413
A flaw was found in the Linux kernel's netfilter ebtables component. This vulnerability involves an uninitialized pointer free that can occur when the system's CPU mask is sparse and a memory allocation fails. Under these specific and unlikely conditions, the kernel might attempt to free an...
CVE-2026-64256
A flaw was found in the Linux kernel's XFS filesystem. This vulnerability occurs in the dqiterate function, where an unsigned 32-bit quota identifier qid can wrap around to zero if it reaches its maximum value. This integer overflow can cause the iteration of quota IDs to restart, potentially...
CVE-2026-64476
A flaw was found in the Linux kernel's vfio/pci driver. The disableidled3 flag, which controls device power states, was handled as a global module parameter instead of being latched per device. This improper handling could lead to unbalanced Power Management PM operations for devices already boun...
CVE-2026-64521
A flaw was found in the Linux kernel's pinctrl subsystem for Amlogic A4 devices. A local attacker could trigger a deadlock by accessing the pinconf-pins sysfs node. This occurs because the pinconfpinsshow function attempts to acquire a mutex that is already held, leading to a system freeze or...
CVE-2026-64272
A flaw was found in the Linux kernel's mms114 touch screen driver. The driver misinterprets the size of touch event data, causing it to read information from incorrect memory locations. This issue, known as an out-of-bounds read, could be exploited by a local attacker to disrupt system operations...
