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: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

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...

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: 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...

CVE-2026-6645

The CVE-2026-6645 vulnerability affects the PaperCut Print Deploy Client for Windows, specifically the pc-printer-updater.exe component. The issue arises when the application performs an internal validation by invoking a secondary system utility without an absolute path, relying on the OS search ...
