CVE-2026-45848

A flaw was found in the Linux kernel's AppArmor security module. This vulnerability allows a local attacker to trigger a NULL pointer dereference during socket setup or teardown operations. This can lead to a kernel 'oops', resulting in a system crash and a Denial of Service DoS...

SUSE CVE-2026-45848

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix NULL sock in aasockfileperm Deal with the potential that sock and sock-sk can be NULL during socket setup or teardown. This could lead to an oops. The fix for NULL pointer dereference in unixneedsrevalidation shows...

SUSE CVE-2026-45918

In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - don't deref NULL sksocket member after tcpclose When deleting a peer in case of keepalive expiration, the peer is removed from the OpenVPN hashtable and is temporary inserted in a "release list" for further processing...

SUSE CVE-2026-45966

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix NULL pointer dereference in unixneedsrevalidation When receiving file descriptors via SCMRIGHTS, both the socket pointer and the socket's sk pointer can be NULL during socket setup or teardown, causing NULL pointer...

SUSE CVE-2026-46027

In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid early lgr access in smcclcwaitmsg A CLC decline can be received while the handshake is still in an early stage, before the connection has been associated with a link group. The decline handling in smcclcwaitmsg...

SUSE CVE-2026-46098

In the Linux kernel, the following vulnerability has been resolved: net: caif: clear client service pointer on teardown caifconnect can tear down an existing client after remote shutdown by calling caifdisconnectclient followed by caiffreeclient. caiffreeclient releases the service layer referenc...

kernel: Bluetooth: SCO: fix race conditions in sco_sock_connect()

A flaw was found in the Linux kernel, specifically within its Bluetooth Synchronous Connection-Oriented SCO component. This vulnerability occurs due to race conditions when multiple connection attempts are made simultaneously on the same Bluetooth socket. This can lead to a use-after-free error,...

kernel: can: j1939: j1939_session_new(): fix skb reference counting

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue does an extra skbget for each new skb, do the same for the initial one in j1939sessionnew to avoid refcount underflow. mkl: clean up commit messag...

CVE-2026-45918

A flaw was found in the Linux kernel's handling of OpenVPN Open Virtual Private Network TCP Transmission Control Protocol connections. A race condition can occur when a userspace process closes a socket while a peer is in the kernel's release list. This can lead to a null pointer dereference when...

CVE-2026-45929

A flaw was found in the Linux kernel's ovpn module. A use-after-free vulnerability exists in the ovpnnetxmit function where a freed skb socket buffer pointer can be used for subsequent operations. This can occur when skbsharecheck frees the original skb if it is shared, leading to a stale pointer...
