https://notcve.org/view.php?id=CVE-2023-52595
In the Linux kernel, the following vulnerability has been resolved: wifi: rt2x00: restart beacon queue when hardware reset When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in hardware interface. However, mac80211 will not automatically stop the queue. If we don't manually stop the beacon queue, the queue will be deadlocked and unable to start again. This patch fixes the issue where Apple devices cannot connect to the AP after calling ieee80211_restart_hw(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: rt2x00: reinicia la cola de baliza cuando se reinicia el hardware Cuando se activa un reinicio de hardware, todos los registros se reinician, por lo que todas las colas se ven obligadas a detenerse en la interfaz de hardware. Sin embargo, mac80211 no detendrá automáticamente la cola. • https://git.kernel.org/stable/c/e1f113b57ddd18274d7c83618deca25cc880bc48 https://git.kernel.org/stable/c/69e905beca193125820c201ab3db4fb0e245124e https://git.kernel.org/stable/c/4cc198580a7b93a36f5beb923f40f7ae27a3716c https://git.kernel.org/stable/c/739b3ccd9486dff04af95f9a890846d088a84957 https://git.kernel.org/stable/c/04cfe4a5da57ab9358cdfadea22bcb37324aaf83 https://git.kernel.org/stable/c/fdb580ed05df8973aa5149cafa598c64bebcd0cb https://git.kernel.org/stable/c/a11d965a218f0cd95b13fe44d0bcd8a20ce134a8 https://lists.debian.org/debian-lts-announce/2024/06/ • CWE-20: Improper Input Validation •

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: Fix potential array-index-out-of-bounds read in ath9k_htc_txstatus() Fix an array-index-out-of-bounds read in ath9k_htc_txstatus(). The bug occurs when txs->cnt, data from a URB provided by a USB device, is bigger than the size of the array txs->txstatus, which is HTC_MAX_TX_STATUS. WARN_ON() already checks it, but there is no bug handling code after the check. Make the function return if that is the case. Found by a modified version of syzkaller.

https://notcve.org/view.php?id=CVE-2023-52593
In the Linux kernel, the following vulnerability has been resolved: wifi: wfx: fix possible NULL pointer dereference in wfx_set_mfp_ap() Since 'ieee80211_beacon_get()' can return NULL, 'wfx_set_mfp_ap()' should check the return value before examining skb data. So convert the latter to return an appropriate error code and propagate it to return from 'wfx_start_ap()' as well. Compile tested only. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: wfx: corrige la posible desreferencia del puntero NULL en wfx_set_mfp_ap() Dado que 'ieee80211_beacon_get()' puede devolver NULL, 'wfx_set_mfp_ap()' debe verificar el valor de retorno antes de examinar los datos de skb. Así que convierta este último para que devuelva un código de error apropiado y propáguelo para que regrese también desde 'wfx_start_ap()'. • https://git.kernel.org/stable/c/574dcd3126aa2eed75437137843f254b1190dd03 https://git.kernel.org/stable/c/9ab224744a47363f74ea29c6894c405e3bcf5132 https://git.kernel.org/stable/c/3739121443f5114c6bcf6d841a5124deb006b878 https://git.kernel.org/stable/c/fe0a7776d4d19e613bb8dd80fe2d78ae49e8b49d •
