kernel: flow_dissector: do not dissect PPPoE PFC frames

A flaw was found in the Linux kernel's flow dissector. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending a specially crafted Point-to-Point Protocol over Ethernet PPPoE Protocol Field Compression PFC frame to an affected system. The incorrect processing of...

kernel: ppp: require CAP_NET_ADMIN in target netns for unattached ioctls

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP subsystem. A local unprivileged user can exploit this vulnerability by creating a new user namespace and bypassing authorization checks for unattached administrative input/output controls ioctls. This allows the user to perform...

kernel: Linux kernel SLIP: Out-of-bounds write due to race condition during MTU change

A flaw was found in the Linux kernel's SLIP Serial Line Internet Protocol network component. A race condition exists during an MTU Maximum Transmission Unit change when the system reallocates receive buffers. This can allow a remote attacker to trigger an out-of-bounds write or write to a freed...

kernel: ipv6: prevent possible UaF in addrconf_permanent_addr()

A flaw was found in the Linux kernel's IPv6 networking subsystem. Specifically, a Use-after-Free UaF vulnerability exists within the addrconfpermanentaddr function. This issue arises when the system attempts to access an IPv6 address after it has been freed, which could allow an attacker to cause...

kernel: dm_early_create: fix freeing used table on dm_resume failure

A flaw was found in the Linux kernel's device mapper DM subsystem. During certain resume operations, the kernel might attempt to free a memory table that has already been released. This error, known as a double-free vulnerability, can lead to memory corruption. A successful exploit could result i...

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: 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: Linux kernel: ALSA timer use-after-free vulnerability allows privilege escalation

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A lack of serialization in the userspace-driven timer utimer TRIGGER ioctl allows two threads to concurrently call sndtimerinterrupt. This race condition can lead to a use-after-free vulnerability, wher...

kernel: soc: qcom: socinfo: Avoid out of bounds read of serial number

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: socinfo: Avoid out of bounds read of serial number On MSM8916 devices, the serial number exposed in sysfs is constant and does not change across individual devices. It's always: db410c:/sys/devices/soc0$ cat serialnumb...

kernel: net: ena: PHC: Fix potential use-after-free in get_timestamp

A flaw was found in the Linux kernel's Elastic Network Adapter ENA driver, specifically within the Precision Time Protocol Hardware Clock PHC timestamp retrieval function. A race condition exists where the gettimestamp function could attempt to access memory that has already been freed by the...

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: net: qrtr: restrict socket creation to the initial network namespace

A flaw was found in the Linux kernel's QRTR Qualcomm IPC Router networking component. An unprivileged local attacker can create a QRTR socket in a separate network namespace. Due to improper handling of global state variables, this allows the attacker to send datagrams and control-plane messages ...

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...

kernel: netfilter: handle unreadable frags

A flaw was found in the Linux kernel's netfilter subsystem. This vulnerability occurs when the u32 module processes network packets containing unreadable fragments, leading to improper handling of these fragments. A remote attacker could exploit this flaw by sending specially crafted network...

kernel: Linux kernel SLIP: Out-of-bounds write due to race condition during MTU change

A flaw was found in the Linux kernel's SLIP Serial Line Internet Protocol network component. A race condition exists during an MTU Maximum Transmission Unit change when the system reallocates receive buffers. This can allow a remote attacker to trigger an out-of-bounds write or write to a freed...

kernel: Linux kernel: ath9k Wi-Fi driver use-after-free vulnerability leading to system crash

A flaw was found in the ath9k Wi-Fi driver in the Linux kernel. A race condition exists during the asynchronous firmware loading process and device disconnection. A local attacker, by repeatedly connecting and disconnecting a malicious USB Wi-Fi device that fails firmware download, could trigger ...

Security update for the Linux Kernel (Live Patch 32 for SUSE Linux Enterprise 15 SP5)

This update for the SUSE Linux Enterprise Kernel 5.14.21-150500.55.127 fixes various security issues: The following security issues were fixed: CVE-2026-46150: fanotify: fix false positive on permission events bsc1267388.
