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 •
CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2023-52458 – block: add check that partition length needs to be aligned with block size
https://notcve.org/view.php?id=CVE-2023-52458
In the Linux kernel, the following vulnerability has been resolved: block: add check that partition length needs to be aligned with block size Before calling add partition or resize partition, there is no check on whether the length is aligned with the logical block size. If the logical block size of the disk is larger than 512 bytes, then the partition size maybe not the multiple of the logical block size, and when the last sector is read, bio_truncate() will adjust the bio size, resulting in an IO error if the size of the read command is smaller than the logical block size.If integrity data is supported, this will also result in a null pointer dereference when calling bio_integrity_free. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bloque: agregar verifique que la longitud de la partición debe estar alineada con el tamaño del bloque Antes de llamar a agregar partición o cambiar el tamaño de la partición, no se verifica si la longitud está alineada con el tamaño del bloque lógico. Si el tamaño del bloque lógico del disco es mayor que 512 bytes, entonces el tamaño de la partición tal vez no sea el múltiplo del tamaño del bloque lógico, y cuando se lea el último sector, bio_truncate() ajustará el tamaño de la biografía, lo que resultará en un error de E/S si el tamaño del comando de lectura es menor que el tamaño del bloque lógico. Si se admiten datos de integridad, esto también resultará en una desreferencia del puntero nulo al llamar a bio_integrity_free. A flaw was found in the Linux kernel's block subsystem, where a NULL pointer dereference occurs if partitions are created or resized with a size that is not a multiple of the logical block size. • https://git.kernel.org/stable/c/8f6dfa1f1efe6dcca2d43e575491d8fcbe922f62 https://git.kernel.org/stable/c/5010c27120962c85d2f421d2cf211791c9603503 https://git.kernel.org/stable/c/ef31cc87794731ffcb578a195a2c47d744e25fb8 https://git.kernel.org/stable/c/cb16cc1abda18a9514106d2ac8c8d7abc0be5ed8 https://git.kernel.org/stable/c/bcdc288e7bc008daf38ef0401b53e4a8bb61bbe5 https://git.kernel.org/stable/c/6f64f866aa1ae6975c95d805ed51d7e9433a0016 https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://access.redhat.com/security/cve/CVE-2023 • CWE-476: NULL Pointer Dereference •
