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 •

https://notcve.org/view.php?id=CVE-2023-52457
In the Linux kernel, the following vulnerability has been resolved: serial: 8250: omap: Don't skip resource freeing if pm_runtime_resume_and_get() failed Returning an error code from .remove() makes the driver core emit the little helpful error message: remove callback returned a non-zero value. This will be ignored. and then remove the device anyhow. So all resources that were not freed are leaked in this case. Skipping serial8250_unregister_port() has the potential to keep enough of the UART around to trigger a use-after-free. So replace the error return (and with it the little helpful error message) by a more useful error message and continue to cleanup. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: serial: 8250: omap: no omita la liberación de recursos si pm_runtime_resume_and_get() falla. • https://git.kernel.org/stable/c/2d66412563ef8953e2bac2d98d2d832b3f3f49cd https://git.kernel.org/stable/c/d833cba201adf9237168e19f0d76e4d7aa69f303 https://git.kernel.org/stable/c/e0db709a58bdeb8966890882261a3f8438c5c9b7 https://git.kernel.org/stable/c/e3f0c638f428fd66b5871154b62706772045f91a https://git.kernel.org/stable/c/02eed6390dbe61115f3e3f63829c95c611aee67b https://git.kernel.org/stable/c/b502fb43f7fb55aaf07f6092ab44657595214b93 https://git.kernel.org/stable/c/bc57f3ef8a9eb0180606696f586a6dcfaa175ed0 https://git.kernel.org/stable/c/828cd829483f0cda920710997aed79130 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2024-26593
In the Linux kernel, the following vulnerability has been resolved: i2c: i801: Fix block process call transactions According to the Intel datasheets, software must reset the block buffer index twice for block process call transactions: once before writing the outgoing data to the buffer, and once again before reading the incoming data from the buffer. The driver is currently missing the second reset, causing the wrong portion of the block buffer to be read. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i2c: i801: Reparar transacciones de llamada de proceso de bloque Según las hojas de datos de Intel, el software debe restablecer el índice del búfer de bloque dos veces para transacciones de llamada de proceso de bloque: una vez antes de escribir los datos salientes en el búfer , y una vez más antes de leer los datos entrantes del búfer. Actualmente, al controlador le falta el segundo reinicio, lo que provoca que se lea la parte incorrecta del búfer de bloque. • https://git.kernel.org/stable/c/315cd67c945351f8a569500f8ab16b7fa94026e8 https://git.kernel.org/stable/c/d074d5ff5ae77b18300e5079c6bda6342a4d44b7 https://git.kernel.org/stable/c/7a14b8a477b88607d157c24aeb23e7389ec3319f https://git.kernel.org/stable/c/1f8d0691c50581ba6043f009ec9e8b9f78f09d5a https://git.kernel.org/stable/c/491528935c9c48bf341d8b40eabc6c4fc5df6f2c https://git.kernel.org/stable/c/6be99c51829b24c914cef5bff6164877178e84d9 https://git.kernel.org/stable/c/609c7c1cc976e740d0fed4dbeec688b3ecb5dce2 https://git.kernel.org/stable/c/c1c9d0f6f7f1dbf29db996bd8e1662428 • CWE-125: Out-of-bounds Read •
