https://notcve.org/view.php?id=CVE-2024-26602
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. Por lo tanto, bloquee la ruta para serializar los accesos y evitar que se llame a una frecuencia demasiado alta y sature la máquina. • https://git.kernel.org/stable/c/22e4ebb975822833b083533035233d128b30e98f https://git.kernel.org/stable/c/3cd139875e9a7688b3fc715264032620812a5fa3 https://git.kernel.org/stable/c/2441a64070b85c14eecc3728cc87e883f953f265 https://git.kernel.org/stable/c/db896bbe4a9c67cee377e5f6a743350d3ae4acf6 https://git.kernel.org/stable/c/50fb4e17df319bb33be6f14e2a856950c1577dee https://git.kernel.org/stable/c/24ec7504a08a67247fbe798d1de995208a8c128a https://git.kernel.org/stable/c/b6a2a9cbb67545c825ec95f06adb7ff300a2ad71 https://git.kernel.org/stable/c/c5b2063c65d05e79fad8029324581d86c •

https://notcve.org/view.php?id=CVE-2024-26601
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') •

CVSS: 7.8EPSS: 0%CPEs: 7EXPL: 0CVE-2024-26598 – KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache
https://notcve.org/view.php?id=CVE-2024-26598
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache There is a potential UAF scenario in the case of an LPI translation cache hit racing with an operation that invalidates the cache, such as a DISCARD ITS command. The root of the problem is that vgic_its_check_cache() does not elevate the refcount on the vgic_irq before dropping the lock that serializes refcount changes. Have vgic_its_check_cache() raise the refcount on the returned vgic_irq and add the corresponding decrement after queueing the interrupt. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: KVM: arm64: vgic-its: Evite posibles UAF en la caché de traducción LPI. Existe un escenario potencial de UAF en el caso de que un caché de traducción LPI se acelere con una operación que invalide la caché, como un comando DISCARD ITS. La raíz del problema es que vgic_its_check_cache() no eleva el refcount en vgic_irq antes de eliminar el bloqueo que serializa los cambios de refcount. • https://git.kernel.org/stable/c/d04acadb6490aa3314f9c9e087691e55de153b88 https://git.kernel.org/stable/c/ba7be666740847d967822bed15500656b26bc703 https://git.kernel.org/stable/c/12c2759ab1343c124ed46ba48f27bd1ef5d2dff4 https://git.kernel.org/stable/c/dba788e25f05209adf2b0175eb1691dc89fb1ba6 https://git.kernel.org/stable/c/65b201bf3e9af1b0254243a5881390eda56f72d1 https://git.kernel.org/stable/c/dd3956a1b3dd11f46488c928cb890d6937d1ca80 https://git.kernel.org/stable/c/ad362fe07fecf0aba839ff2cc59a3617bd42c33f https://lists.debian.org/debian-lts-announce/2024/06/ • CWE-416: Use After Free •
