https://notcve.org/view.php?id=CVE-2021-47182
In the Linux kernel, the following vulnerability has been resolved: scsi: core: Fix scsi_mode_sense() buffer length handling Several problems exist with scsi_mode_sense() buffer length handling: 1) The allocation length field of the MODE SENSE(10) command is 16-bits, occupying bytes 7 and 8 of the CDB. With this command, access to mode pages larger than 255 bytes is thus possible. However, the CDB allocation length field is set by assigning len to byte 8 only, thus truncating buffer length larger than 255. 2) If scsi_mode_sense() is called with len smaller than 8 with sdev->use_10_for_ms set, or smaller than 4 otherwise, the buffer length is increased to 8 and 4 respectively, and the buffer is zero filled with these increased values, thus corrupting the memory following the buffer. Fix these 2 problems by using put_unaligned_be16() to set the allocation length field of MODE SENSE(10) CDB and by returning an error when len is too small. Furthermore, if len is larger than 255B, always try MODE SENSE(10) first, even if the device driver did not set sdev->use_10_for_ms. In case of invalid opcode error for MODE SENSE(10), access to mode pages larger than 255 bytes are not retried using MODE SENSE(6). To avoid buffer length overflows for the MODE_SENSE(10) case, check that len is smaller than 65535 bytes. While at it, also fix the folowing: * Use get_unaligned_be16() to retrieve the mode data length and block descriptor length fields of the mode sense reply header instead of using an open coded calculation. * Fix the kdoc dbd argument explanation: the DBD bit stands for Disable Block Descriptor, which is the opposite of what the dbd argument description was. • https://git.kernel.org/stable/c/e15de347faf4a9f494cbd4e9a623d343dc1b5851 https://git.kernel.org/stable/c/17b49bcbf8351d3dbe57204468ac34f033ed60bc •

CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-52340 – kernel: ICMPv6 “Packet Too Big” packets force a DoS of the Linux kernel by forcing 100% CPU
https://notcve.org/view.php?id=CVE-2023-52340
The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket. La implementación de IPv6 en el kernel de Linux anterior a 6.3 tiene un umbral net/ipv6/route.c max_size que se puede consumir fácilmente, por ejemplo, provocando una denegación de servicio (errores de red inaccesible) cuando los paquetes IPv6 se envían en un bucle a través de un enchufe crudo. A flaw in the routing table size was found in the ICMPv6 handling of "Packet Too Big". The size of the routing table is regulated by periodic garbage collection. However, with "Packet Too Big Messages" it is possible to exceed the routing table size and garbage collector threshold. • https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=af6d10345ca76670c1b7c37799f0d5576ccef277 https://access.redhat.com/security/cve/CVE-2023-52340 https://bugzilla.redhat.com/show_bug.cgi?id=2257979 • CWE-400: Uncontrolled Resource Consumption •

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate payload size in ipc response If installing malicious ksmbd-tools, ksmbd.mountd can return invalid ipc response to ksmbd kernel server. ksmbd should validate payload size of ipc response from ksmbd.mountd to avoid memory overrun or slab-out-of-bounds. This patch validate 3 ipc response that has payload. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ksmbd: validar el tamaño del payload en la respuesta de ipc Si instala herramientas ksmbd maliciosas, ksmbd.mountd puede devolver una respuesta de ipc no válida al servidor del kernel de ksmbd. ksmbd debe validar el tamaño del payload de la respuesta ipc de ksmbd.mountd para evitar el desbordamiento de la memoria o los límites.

https://notcve.org/view.php?id=CVE-2024-26791
In the Linux kernel, the following vulnerability has been resolved: btrfs: dev-replace: properly validate device names There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: btrfs: dev-replace: validar correctamente los nombres de los dispositivos. Hay un informe de syzbot que indica que los búferes de nombres de dispositivos pasados para reemplazar el dispositivo no se verifican adecuadamente para determinar la terminación de la cadena, lo que podría provocar una lectura fuera de los límites. en getname_kernel(). Agregue un asistente que valide los búferes de nombres de dispositivos de origen y de destino. Para devid como fuente, inicialice el búfer en una cadena vacía en caso de que algo intente leerlo más tarde. • https://git.kernel.org/stable/c/11d7a2e429c02d51e2dc90713823ea8b8d3d3a84 https://git.kernel.org/stable/c/c6652e20d7d783d060fe5f987eac7b5cabe31311 https://git.kernel.org/stable/c/2886fe308a83968dde252302884a1e63351cf16d https://git.kernel.org/stable/c/ab2d68655d0f04650bef09fee948ff80597c5fb9 https://git.kernel.org/stable/c/f590040ce2b712177306b03c2a63b16f7d48d3c8 https://git.kernel.org/stable/c/b1690ced4d2d8b28868811fb81cd33eee5aefee1 https://git.kernel.org/stable/c/343eecb4ff49a7b1cc1dfe86958a805cf2341cfb https://git.kernel.org/stable/c/9845664b9ee47ce7ee7ea93caf47d39a9 •
