01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject cooked mode if it is set along with other flags It is possible to set both MONITOR_FLAG_COOK_FRAMES and MONITOR_FLAG_ACTIVE flags simultaneously on the same monitor interface from the userspace. This causes a sub-interface to be created with no IEEE80211_SDATA_IN_DRIVER bit set because the monitor interface is in the cooked state and it takes precedence over all other states. When the interface is then being deleted th... • https://git.kernel.org/stable/c/66f7ac50ed7cc5c19a62bc97e8f6e7891004a03a •

01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: limit printed string from FW file There's no guarantee here that the file is always with a NUL-termination, so reading the string may read beyond the end of the TLV. If that's the last TLV in the file, it can perhaps even read beyond the end of the file buffer. Fix that by limiting the print format to the size of the buffer we have. • https://git.kernel.org/stable/c/aee1b6385e29e472ae5592b9652b750a29bf702e •

01 Apr 2025 — In the Linux kernel, the following vulnerability has been resolved: caif_virtio: fix wrong pointer check in cfv_probe() del_vqs() frees virtqueues, therefore cfv->vq_tx pointer should be checked for NULL before calling it, not cfv->vdev. Also the current implementation is redundant because the pointer cfv->vdev is dereferenced before it is checked for NULL. Fix this by checking cfv->vq_tx for NULL instead of cfv->vdev before calling del_vqs(). • https://git.kernel.org/stable/c/0d2e1a2926b1839a4b74519e660739b2566c9386 •

When first_ip is 0, last_ip is 0xFFFFFFFF, and netmask is 31, the value of an arithmetic expression 2 << (netmask - mask_bits - 1) is subject to overflow due to a failure casting operands to a larger data type before performing the arithmetic.
