This condition arises when a connection object is accessed afte...

kernel: net: qrtr: fix refcount saturation and potential UAF in qrtr_port_remove

A flaw was found in the Linux kernel's qrtr network subsystem. A race condition exists in the qrtrportremove function where the socket reference count is decremented prematurely. This allows a concurrent reader to access a socket whose reference count has dropped to zero, potentially leading to a...

kernel: wifi: nl80211: reject oversized EMA RNR lists

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211parsernrelems function, responsible for parsing EMA RNR Enhanced Multiple Access Reduced Neighbor Report lists, does not properly handle an excessive number of nested NL80211ATTREMARNRELEMS inputs. This improper input...

kernel: Bluetooth: hci_sync: fix UAF in hci_le_create_cis_sync

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability, a Use-After-Free UAF, allows an attacker to access memory after it has been freed. This can lead to a system crash, resulting in a Denial of Service DoS, or potentially enable an attacker to execute malicious code. Th...

Linux Kernel Crypto Subsystem Use-After-Free Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of...

Linux Kernel FUSE Subsystem Race Condition Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of fusereq...

Linux Kernel SCTP Subsystem Race Condition Information Disclosure Vulnerability

This vulnerability allows local attackers to disclose sensitive information on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processi...

CVE-2026-89749

A flaw was found in the Linux kernel. Specifically, within the tracing subsystem, the eventteststuff function can pass an invalid error pointer to kthreadstop if kthreadrun fails to create a kernel thread. This improper handling of error pointers, particularly under memory pressure, leads to...

CVE-2026-89522

A flaw was found in the Linux kernel's media subsystem, specifically within the ipu7 driver. When an error occurs during the device's initial setup probe error path, a V4L2 asynchronous notifier is not correctly removed from a global list. This results in a use-after-free vulnerability, where the...

CVE-2026-89570

A flaw was found in the Linux kernel's Compute Express Link CXL subsystem. Lifetime issues with the CXL Machine Check Exception MCE notifier can lead to NULL dereferences and use-after-free vulnerabilities in the MCE handler. This could allow an attacker to cause system instability or a denial of...

CVE-2026-89486

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. Due to incorrect synchronization during the deallocation of command receiver objects, a use-after-free vulnerability can occur. This allows a freed memory region to be accessed, which could be exploit...

CVE-2026-89462

A flaw was found in the Linux kernel's power supply subsystem, specifically within the max17040 driver. This vulnerability occurs when the max17040getvcell and max17040getsoc functions fail to properly handle errors returned by regmapread during an I2C transfer. As a result, uninitialized registe...

CVE-2026-81008
