In the Linux kernel, the following vulnerability has been resolved: phonet: fix rtm_phonet_notify() skb allocation fill_route() stores three components in the skb: - struct rtmsg - RTA_DST (u8) - RTA_OIF (u32) Therefore, rtm_phonet_notify() should use NLMSG_ALIGN(sizeof(struct rtmsg)) + nla_total_size(1) + nla_total_size(4) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phonet: corrige la asignación de skb de rtm_phonet_notify() fill_route() almacena tres componentes en el skb: - struct rtmsg - RTA_DST (u8) - RTA_OIF (u32) Por lo tanto, rtm_phonet_notify() debería usar NLMSG_ALIGN(tamañode(struct rtmsg)) + nla_total_size(1) + nla_total_size(4) • https://git.kernel.org/stable/c/f062f41d06575744b9eaf725eef8a5d3b5f5b7ca https://git.kernel.org/stable/c/ec1f71c05caeba0f814df77e0f511d8b4618623a https://git.kernel.org/stable/c/dc6beac059f0331de97155a89d84058d4a9e49c7 https://git.kernel.org/stable/c/f085e02f0a32f6dfcfabc6535c9c4a1707cef86b https://git.kernel.org/stable/c/4ff334cade9dae50e4be387f71e94fae634aa9b4 https://git.kernel.org/stable/c/728a83160f98ee6b60df0d890141b9b7240182fe https://git.kernel.org/stable/c/ee9e39a6cb3ca2a3d35b4ae25547ee3526a44d00 https://git.kernel.org/stable/c/9a77226440008cf04ba68faf641a2d50f •

https://notcve.org/view.php?id=CVE-2024-36944
In the Linux kernel, the following vulnerability has been resolved: Reapply "drm/qxl: simplify qxl_fence_wait" This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds" and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking. Reverting the commit allows Steve's VM to boot to completion again. [ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Vuelva a aplicar "drm/qxl: simplificar qxl_fence_wait" Esto revierte el commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt informa: "Fui a ejecutar mis pruebas en mis máquinas virtuales y las pruebas se colgaron al arrancar. Desafortunadamente, lo máximo que obtuve fue: [ 93.607888] Probando evento de initcall del sistema: OK [ 93.667730] Ejecutando pruebas en todos los eventos de seguimiento : [93.669757] Probando todos los eventos: OK [95.631064] ------------[ cortar aquí ]------------ Se agotó el tiempo de espera después de 60 segundos" y más puntos de depuración a una posible dependencia de bloqueo circular entre el bloqueo del propietario de la consola y el bloqueo del grupo de trabajadores.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix firmware check error path A recent commit fixed the code that parses the firmware files before downloading them to the controller but introduced a memory leak in case the sanity checks ever fail. Make sure to free the firmware buffer before returning on errors. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: qca: corregir ruta de error de verificación de firmware Una confirmación reciente corrigió el código que analiza los archivos de firmware antes de descargarlos al controlador, pero introdujo una pérdida de memoria en caso de que las comprobaciones de cordura alguna vez fallaran.

CVSS: 2.3EPSS: 0%CPEs: 8EXPL: 0CVE-2024-36940 – pinctrl: core: delete incorrect free in pinctrl_enable()
https://notcve.org/view.php?id=CVE-2024-36940
In the Linux kernel, the following vulnerability has been resolved: pinctrl: core: delete incorrect free in pinctrl_enable() The "pctldev" struct is allocated in devm_pinctrl_register_and_init(). It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(), so freeing it in pinctrl_enable() will lead to a double free. The devm_pinctrl_dev_release() function frees the pindescs and destroys the mutex as well. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pinctrl: core: eliminar incorrecto gratis en pinctrl_enable() La estructura "pctldev" está asignada en devm_pinctrl_register_and_init(). Es un puntero administrado por devm_ que se libera mediante devm_pinctrl_dev_release(), por lo que liberarlo en pinctrl_enable() generará una doble liberación. La función devm_pinctrl_dev_release() libera los pindescs y también destruye el mutex. • https://git.kernel.org/stable/c/6118714275f0a313ecc296a87ed1af32d9691bed https://git.kernel.org/stable/c/735f4c6b6771eafe336404c157ca683ad72a040d https://git.kernel.org/stable/c/cdaa171473d98962ae86f2a663d398fda2fbeefd https://git.kernel.org/stable/c/288bc4aa75f150d6f1ee82dd43c6da1b438b6068 https://git.kernel.org/stable/c/41f88ef8ba387a12f4a2b8c400b6c9e8e54b2cca https://git.kernel.org/stable/c/ac7d65795827dc0cf7662384ed27caf4066bd72e https://git.kernel.org/stable/c/558c8039fdf596a584a92c171cbf3298919c448c https://git.kernel.org/stable/c/f9f1e321d53e4c5b666b66e5b43da2984 • CWE-415: Double Free •
