https://notcve.org/view.php?id=CVE-2023-52469
In the Linux kernel, the following vulnerability has been resolved: drivers/amd/pm: fix a use-after-free in kv_parse_power_table When ps allocated by kzalloc equals to NULL, kv_parse_power_table frees adev->pm.dpm.ps that allocated before. However, after the control flow goes through the following call chains: kv_parse_power_table |-> kv_dpm_init |-> kv_dpm_sw_init |-> kv_dpm_fini The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after its first free in kv_parse_power_table and causes a use-after-free bug. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/amd/pm: corrige un use-after-free en kv_parse_power_table Cuando ps asignado por kzalloc es igual a NULL, kv_parse_power_table libera adev->pm.dpm.ps que se asignó antes. Sin embargo, después de que el flujo de control pasa por las siguientes cadenas de llamadas: kv_parse_power_table |-> kv_dpm_init |-> kv_dpm_sw_init |-> kv_dpm_fini El adev->pm.dpm.ps se usa en el bucle for de kv_dpm_fini después de su primera liberación en kv_parse_power_table y provoca un error de use-after-free. A use-after-free flaw was found in kv_parse_power_table in drivers/amd/pm in the Linux kernel. • https://git.kernel.org/stable/c/a2e73f56fa6282481927ec43aa9362c03c2e2104 https://git.kernel.org/stable/c/8a27d9d9fc9b5564b8904c3a77a7dea482bfa34e https://git.kernel.org/stable/c/8b55b06e737feb2a645b0293ea27e38418876d63 https://git.kernel.org/stable/c/520e213a0b97b64735a13950e9371e0a5d7a5dc3 https://git.kernel.org/stable/c/b6dcba02ee178282e0d28684d241e0b8462dea6a https://git.kernel.org/stable/c/35fa2394d26e919f63600ce631e6aefc95ec2706 https://git.kernel.org/stable/c/95084632a65d5c0d682a83b55935560bdcd2a1e3 https://git.kernel.org/stable/c/3426f059eacc33ecc676b0d66539297e1 • CWE-416: Use After Free •

In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sched/membarrier: reduce la capacidad de martillar en sys_membarrier. En algunos sistemas, sys_membarrier puede ser muy costoso, provocando ralentizaciones generales en todo.

In the Linux kernel, the following vulnerability has been resolved: ext4: regenerate buddy after block freeing failed if under fc replay This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on code in mb_free_blocks(), fast commit replay can end up marking as free blocks that are already marked as such. This causes corruption of the buddy bitmap so we need to regenerate it in that case. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ext4: regenerar amigo después de que falló la liberación del bloque si se encuentra en reproducción fc. Esto revierte principalmente el commit 6bd97bf273bd ("ext4: eliminar mb_regenerate_buddy() redundante") y reintroduce mb_regenerate_buddy(). • https://git.kernel.org/stable/c/0983142c5f17a62055ec851372273c3bc77e4788 https://git.kernel.org/stable/c/6bd97bf273bdb4944904e57480f6545bca48ad77 https://git.kernel.org/stable/c/94ebf71bddbcd4ab1ce43ae32c6cb66396d2d51a https://git.kernel.org/stable/c/c1317822e2de80e78f137d3a2d99febab1b80326 https://git.kernel.org/stable/c/78327acd4cdc4a1601af718b781eece577b6b7d4 https://git.kernel.org/stable/c/ea42d6cffb0dd27a417f410b9d0011e9859328cb https://git.kernel.org/stable/c/6b0d48647935e4b8c7b75d1eccb9043fcd4ee581 https://git.kernel.org/stable/c/c9b528c35795b711331ed36dc3dbee90d • CWE-118: Incorrect Access of Indexable Resource ('Range Error') •
