https://notcve.org/view.php?id=CVE-2024-35835
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a double-free in arfs_create_groups When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net/mlx5e: corregido un double free en arfs_create_groups Cuando falla `in` asignado por kvzalloc, arfs_create_groups liberará ft->g y devolverá un error. Sin embargo, arfs_create_table, el único llamador de arfs_create_groups, mantendrá este error y llamará a mlx5e_destroy_flow_table, en el que ft->g se liberará nuevamente. A double-free vulnerability was found in the `arfs_create_groups` function in the Linux kernel's `net/mlx5e` driver. • https://git.kernel.org/stable/c/1cabe6b0965ec067ac60e8f182f16d479a3b9a5c https://git.kernel.org/stable/c/e3d3ed8c152971dbe64c92c9ecb98fdb52abb629 https://git.kernel.org/stable/c/2501afe6c4c9829d03abe9a368b83d9ea1b611b7 https://git.kernel.org/stable/c/cf116d9c3c2aebd653c2dfab5b10c278e9ec3ee5 https://git.kernel.org/stable/c/c57ca114eb00e03274dd38108d07a3750fa3c056 https://git.kernel.org/stable/c/42876db001bbea7558e8676d1019f08f9390addb https://git.kernel.org/stable/c/b21db3f1ab7967a81d6bbd328d28fe5a4c07a8a7 https://git.kernel.org/stable/c/66cc521a739ccd5da057a1cb3d6346c6d •

https://notcve.org/view.php?id=CVE-2023-52672
In the Linux kernel, the following vulnerability has been resolved: pipe: wakeup wr_wait after setting max_usage Commit c73be61cede5 ("pipe: Add general notification queue support") a regression was introduced that would lock up resized pipes under certain conditions. See the reproducer in [1]. The commit resizing the pipe ring size was moved to a different function, doing that moved the wakeup for pipe->wr_wait before actually raising pipe->max_usage. If a pipe was full before the resize occured it would result in the wakeup never actually triggering pipe_write. Set @max_usage and @nr_accounted before waking writers if this isn't a watch queue. [Christian Brauner <brauner@kernel.org>: rewrite to account for watch queues] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tubería: despertar wr_wait después de configurar max_usage Confirmar c73be61cede5 ("tubería: Agregar soporte de cola de notificaciones generales") se introdujo una regresión que bloquearía las tuberías redimensionadas bajo ciertas condiciones. Ver el reproductor en [1]. La confirmación de cambio de tamaño del anillo de tubería se movió a una función diferente, lo que movió la activación de pipe->wr_wait antes de aumentar pipe->max_usage. • https://git.kernel.org/stable/c/c73be61cede5882f9605a852414db559c0ebedfd https://git.kernel.org/stable/c/162ae0e78bdabf84ef10c1293c4ed7865cb7d3c8 https://git.kernel.org/stable/c/3efbd114b91525bb095b8ae046382197d92126b9 https://git.kernel.org/stable/c/b87a1229d8668fbc78ebd9ca0fc797a76001c60f https://git.kernel.org/stable/c/68e51bdb1194f11d3452525b99c98aff6f837b24 https://git.kernel.org/stable/c/6fb70694f8d1ac34e45246b0ac988f025e1e5b55 https://git.kernel.org/stable/c/e95aada4cb93d42e25c30a0ef9eb2923d9711d4a https://lists.debian.org/debian-lts-announce/2024/06/ • CWE-400: Uncontrolled Resource Consumption •
