kernel: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: handle NULL sock pointer in l2capsockalloc A NULL sock pointer is passed into l2capsockalloc when it is called from l2capsocknewconnectioncb and the error handling paths should also be aware of it. Seemingly a...

kernel: sock_map: avoid race between sock_map_close and sk_psock_put

In the Linux kernel, the following vulnerability has been resolved: sockmap: avoid race between sockmapclose and skpsockput skpsockget will return NULL if the refcount of psock has gone to 0, which will happen when the last call of skpsockput is done. However, skpsockdrop may not have finished ye...

kernel: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create()

A user-after-free vulnerability was found in the linux kernel. sockinitdata attaches the allocated sk object to the provided sock object. If ieee802154create fails later, the allocated sk object is freed, but the dangling pointer remains in the provided sock object, leading to a crash and loss of...

AZL-69665 CVE-2025-23143 affecting package kernel for versions less than 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: net: Fix null-ptr-deref by socklockinitclassandname and rmmod. When I ran the repro 0 and waited a few seconds, I observed two LOCKDEP splats: a warning immediately followed by a null-ptr-deref. 1 Reproduction Steps: 1 Mount CIFS...

CVE-2025-23143

CVE-2025-23143 is a Linux kernel issue where unloading a module (e.g., CIFS/NFS) can race with a TCP socket still alive, leading to a NULL pointer dereference in lockdep when hlock_class() is called after the module is gone. The root cause is that CIFS assigns a different lock class to the socket...
