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: 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 ...

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...
