SUSE-SU-2026:4254-1 Security update for the Linux Kernel

The SUSE Linux Enterprise 15 SP7 kernel was updated to fix various security issues: The following security issues were fixed: - CVE-2024-57841,CVE-2026-53260: net: fix memory leak in tcpconnrequest bsc1235944 bsc1269731. - CVE-2025-68214: timers: Fix NULL function pointer race in timershutdownsyn...

kernel: wifi: iwlwifi: mld: stop TX during firmware restart

A flaw was found in the Linux kernel's iwlwifi driver. When the Wi-Fi firmware crashes, the driver continues to process network transmission requests inefficiently. This creates a continuous loop of attempting to send data through an unresponsive firmware, consuming excessive CPU resources and...

kernel: wifi: iwlwifi: mvm: fix driver-set TX rates on old devices

A flaw was found in the Linux kernel's iwlwifi driver, affecting older Intel wireless devices. This vulnerability arises from incorrect handling of transmit TX rates, specifically when the driver attempts to set these rates. An attacker could potentially trigger a firmware assert or crash, leadin...

kernel: ALSA: seq: Serialize UMP output teardown with event_input

A flaw was found in the Advanced Linux Sound Architecture ALSA sequencer component of the Linux kernel. This vulnerability, a use-after-free, occurs because of improper synchronization when handling Universal MIDI Packet UMP output. A local attacker could exploit this by creating a specific timin...

kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

kernel: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check

A flaw was found in the Linux kernel's netfilter conntrack TCP state machine. A remote attacker can exploit this vulnerability by sending a specially crafted sequence of TCP Transmission Control Protocol packets, specifically a SYN synchronize packet followed by an RST reset packet with an invali...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

kernel: xfrm: hold dev ref until after transport_finish NF_HOOK

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...

kernel: RDMA/rxe: Reject non-8-byte ATOMIC_WRITE payloads

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access subsystem, specifically within the rxe driver. A remote attacker could exploit this vulnerability by sending a specially crafted ATOMICWRITE request with a zero-byte payload. This improper handling of non-8-byte ATOMICWRITE...

kernel: selinux: check connect-related permissions on TCP Fast Open

A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux module. When using TCP Fast Open, SELinux failed to properly check connect-related permissions. This oversight could allow a local attacker to bypass SELinux network access controls, potentially enabling unauthorized network...

kernel: ALSA: timer: Fix UAF at snd_timer_user_params()

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A race condition can occur during the release of a timer object, specifically when the SNDRVTIMERIOCTLPARAMS ioctl is called concurrently. This can lead to a use-after-free vulnerability, potentially...
