kernel: netfilter: ctnetlink: ensure safe access to master conntrack

A flaw was found in the netfilter: ctnetlink component of the Linux kernel. This vulnerability occurs due to insufficient locking when accessing the master conntrack object, allowing it to become invalid while still being referenced. A local attacker could potentially exploit this race condition,...

kernel: Linux kernel: smb: client: reject userspace cifs.spnego descriptions

A privilege escalation vulnerability was found in the Linux kernel's CIFS client implementation. This could allow a local attacker to impersonate other users, bypass authentication in SMB mount operations, and potentially gain unauthorized access to network file shares or escalate privileges...

A flaw was found in the netfilter: ctnetlink component of the Linux kernel. This vulnerability occurs due to insufficient locking when accessing the master conntrack object, allowing it to become invalid while still being referenced. A local attacker could potentially exploit this race condition,...

kernel: Linux kernel: Use-after-free in BPF sockmap can lead to denial of service and privilege escalation

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap subsystem. A race condition exists where the sksocket is not properly locked or referenced during the skbsendsock function call, allowing for a use-after-free vulnerability. This can be exploited by a local attacker, leadin...

kernel: can: isotp: fix tx.buf use-after-free in isotp_sendmsg()

A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP isotp module. This vulnerability, known as a use-after-free, occurs when the system attempts to free a memory region while it is still being used. A local attacker could trigger this condition by sending a signal that...

kernel: ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

A flaw was found in the Linux kernel. A local attacker can exploit an out-of-bounds write vulnerability when the kernel recomputes an IPv6 Source Routing Header SRH. This issue occurs because insufficient headroom is reserved during the recompression process, leading to memory corruption...

kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...

CVE-2026-6645

An insecure process execution vulnerability exists in the pc-printer-updater.exe component of the PaperCut Print Deploy Client for Windows. The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system...

PT-2026-51334

Name of the Vulnerable Software and Affected Versions qSnapper versions prior to 1.3.3 Description Lack of authentication when using the snapshot diff functions allows a local attacker to access information that is otherwise read protected. Recommendations Update to version 1.3.3 or later...

PT-2026-51335

Name of the Vulnerable Software and Affected Versions qSnapper versions prior to 1.3.3 Description Incorrect caching of authentication between different polkit PolicyKit, a component for controlling privileges in Unix-like operating systems methods allows a local attacker to perform unauthorized...

PT-2026-51336

Name of the Vulnerable Software and Affected Versions qSnapper versions prior to 1.3.3 Description The qSnapper dbus service incorrectly caches authentication between different users. This allows a local attacker to utilize dbus functions after a privileged user has already performed authenticati...

PT-2026-51274

PT-2026-51333

Name of the Vulnerable Software and Affected Versions qSnapper versions prior to 1.3.3 Description A path traversal issue exists when using the configName parameter. This allows a local attacker to utilize malicious configuration files for snapper, which can lead to a denial of service or potenti...

CVE-2026-12779

CVE-2026-12779 affects AOMEI Dynamic Disk Manager up to version 10.10.1, specifically its Kernel Driver component ddmdrv.sys. The issue arises from improper access controls in a local-processing path within the ddmdrv.sys library. The vulnerability is locally exploitable, with an exploit publicly...

kernel: exit: prevent preemption of oopsing TASK_DEAD task

A flaw was found in the Linux kernel. During the exit process of a task that has encountered an error, the system can incorrectly allow the task to be interrupted. This can lead to improper management of the task's memory, potentially causing memory corruption. Such an issue could allow a local...
