https://notcve.org/view.php?id=CVE-2024-38619
In the Linux kernel, the following vulnerability has been resolved: usb-storage: alauda: Check whether the media is initialized The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba(). - Add a member "media_initialized" to struct alauda_info. - Change a condition in alauda_check_media() to ensure the first initialization. - Add an error check for the return value of alauda_init_media(). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb-storage: alauda: compruebe si el medio está inicializado. El miembro "uzonesize" de la estructura alauda_info permanecerá 0 si alauda_init_media() falla, lo que podría provocar errores de división en alauda_read_data() y alauda_write_lba(). - Agregue un miembro "media_initialized" a la estructura alauda_info. - Cambiar una condición en alauda_check_media() para asegurar la primera inicialización. - Agregue una verificación de errores para el valor de retorno de alauda_init_media(). • https://git.kernel.org/stable/c/e80b0fade09ef1ee67b0898d480d4c588f124d5f https://git.kernel.org/stable/c/e0aab7b07a9375337847c9d74a5ec044071e01c8 https://git.kernel.org/stable/c/51fe16c058acb22f847e69bc598066ed0bcd5c15 https://git.kernel.org/stable/c/f68820f1256b21466ff094dd97f243b7e708f9c1 https://git.kernel.org/stable/c/3eee13ab67f65606faa66e0c3c729e4f514838fd https://git.kernel.org/stable/c/e0e2eec76920a133dd49a4fbe4656d83596a1361 https://git.kernel.org/stable/c/2cc32639ec347e3365075b130f9953ef16cb13f1 https://git.kernel.org/stable/c/24bff7f714bdff97c2a75a0ff6a368cdf • CWE-457: Use of Uninitialized Variable •

https://notcve.org/view.php?id=CVE-2021-47609
In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scpi: Fix string overflow in SCPI genpd driver Without the bound checks for scpi_pd->name, it could result in the buffer overflow when copying the SCPI device name from the corresponding device tree node as the name string is set at maximum size of 30. Let us fix it by using devm_kasprintf so that the string buffer is allocated dynamically. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: arm_scpi: corrige el desbordamiento de cadena en el controlador SCPI genpd. Sin las comprobaciones vinculadas para scpi_pd->name, podría provocar un desbordamiento del búfer al copiar el nombre del dispositivo SCPI del dispositivo correspondiente. El nodo del árbol como cadena de nombre se establece en un tamaño máximo de 30. Arreglemoslo usando devm_kasprintf para que el búfer de cadena se asigne dinámicamente. • https://git.kernel.org/stable/c/8bec4337ad4023b26de35d3b0c3a3b2735ffc5c7 https://git.kernel.org/stable/c/639901b9429a3195e0fead981ed74b51f5f31538 https://git.kernel.org/stable/c/4694b1ec425a2d20d6f8ca3db594829fdf5f2672 https://git.kernel.org/stable/c/7e8645ca2c0046f7cd2f0f7d569fc036c8abaedb https://git.kernel.org/stable/c/802a1a8501563714a5fe8824f4ed27fec04a0719 https://git.kernel.org/stable/c/f0f484714f35d24ffa0ecb4afe3df1c5b225411d https://git.kernel.org/stable/c/976389cbb16cee46847e5d06250a3a0b5506781e https://git.kernel.org/stable/c/865ed67ab955428b9aa771d8b4f1e4fb7 • CWE-787: Out-of-bounds Write •
