In the Linux kernel, the following vulnerability has been resolved: kcov: fix data corruption and race conditions on PREEMPTRT syzbot is reporting KCOV state corruption on PREEMPTRT kernels, for the temporary storage used for saving/restoring remote KCOV state is currently allocated as the per-CP...

CVE-2026-80916

CVE-2026-80916 affects the Linux kernel KCOV subsystem on PREEMPT_RT builds. The root cause is that temporary storage for saving/restoring remote KCOV state was allocated in the per-CPU area ; when a softirq thread preempts a task running a remote KCOV session and is itself preempted by a higher-...

CVE-2026-80914 Bluetooth: ISO: fix use-after-free of listener socket in iso_conn_ready

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix use-after-free of listener socket in isoconnready isoconnready looks up the BIS listener socket with isogetsock, which takes a reference, and then, without re-checking its state, creates a child socket from it...

CVE-2026-80914

CVE-2026-80914 is a use-after-free vulnerability in the Linux kernel's Bluetooth ISO subsystem , specifically in the iso_conn_ready() function. When a BIS listener socket is closed concurrently between iso_get_sock() and lock_sock(), the socket may be freed while a child socket remains linked to ...

kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...

kernel: rhashtable: clear stale iter->p on table restart

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

kernel: smb: client: validate DFS referral PathConsumed

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...

kernel: netfilter: conntrack: remove sprintf usage

A flaw was found in the Linux kernel's netfilter conntrack module. This vulnerability arises from the use of sprintf and insufficient buffer sizing in the manglecontentlen function, which can lead to a stack-out-of-bounds write. An attacker could potentially exploit this memory corruption issue t...

kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests

A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...

kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...
