CVE-2026-64386
A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...
CVE-2026-64353
A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs because the BPF verifier incorrectly handles dynamic inner array lookups in ARRAYOFMAPS. When an inner map template is replaced by a concrete inner array with a different maximum entry size, the...
CVE-2026-64339
A flaw was found in the Linux kernel's USB subsystem, specifically within the usbio module. A malicious or malfunctioning Universal Serial Bus USB device can exploit this vulnerability by providing crafted input during a bulk IN transfer. This can lead to an out-of-bounds read, allowing the devic...
CVE-2026-64549
A flaw was found in the Linux kernel's Bluetooth bpa10x driver. This vulnerability allows a malicious Bluetooth device to trigger an out-of-bounds read in the bpa10xsetup function by sending a specially crafted one-byte or non-NUL-terminated response. This can lead to information disclosure, wher...
kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle
A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...
kernel: tipc: fix double-free in tipc_buf_append()
A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...
kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle
A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...
kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns
A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...
kernel: fanotify: fix false positive on permission events
A flaw was found in the Linux kernel's fanotify subsystem. This vulnerability allows for a bypass of permission checks because the fsnotifygetmarksafe function may incorrectly return false for marks on unrelated groups. This could enable an attacker to perform unauthorized actions by circumventin...

kernel: ipc: limit next_id allocation to the valid ID range
A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...
USN-8620-4: 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...

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...
