https://notcve.org/view.php?id=CVE-2024-36947
In the Linux kernel, the following vulnerability has been resolved: qibfs: fix dentry leak simple_recursive_removal() drops the pinning references to all positives in subtree. For the cases when its argument has been kept alive by the pinning alone that's exactly the right thing to do, but here the argument comes from dcache lookup, that needs to be balanced by explicit dput(). Fucked-up-by: Al Viro <viro@zeniv.linux.org.uk> En el kernel de Linux, se resolvió la siguiente vulnerabilidad: qibfs: arreglar la fuga de dentry simple_recursive_removal() elimina las referencias de fijación a todos los positivos en el subárbol. Para los casos en los que su argumento se ha mantenido vivo solo mediante la fijación, eso es exactamente lo correcto, pero aquí el argumento proviene de la búsqueda de dcache, que debe equilibrarse con dput() explícito.

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 •

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.

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.
