https://notcve.org/view.php?id=CVE-2024-35992
In the Linux kernel, the following vulnerability has been resolved: phy: marvell: a3700-comphy: Fix out of bounds read There is an out of bounds read access of 'gbe_phy_init_fix[fix_idx].addr' every iteration after 'fix_idx' reaches 'ARRAY_SIZE(gbe_phy_init_fix)'. Make sure 'gbe_phy_init[addr]' is used when all elements of 'gbe_phy_init_fix' array are handled. Found by Linux Verification Center (linuxtesting.org) with SVACE. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phy: marvell: a3700-comphy: corrección de lectura fuera de los límites. Hay un acceso de lectura fuera de los límites de 'gbe_phy_init_fix[fix_idx].addr' en cada iteración después de que 'fix_idx' alcance ' ARRAY_SIZE(gbe_phy_init_fix)'. Asegúrese de que se utilice 'gbe_phy_init[addr]' cuando se manejen todos los elementos de la matriz 'gbe_phy_init_fix'.

https://notcve.org/view.php?id=CVE-2024-35988
In the Linux kernel, the following vulnerability has been resolved: riscv: Fix TASK_SIZE on 64-bit NOMMU On NOMMU, userspace memory can come from anywhere in physical RAM. The current definition of TASK_SIZE is wrong if any RAM exists above 4G, causing spurious failures in the userspace access routines. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv: corrige TASK_SIZE en NOMMU de 64 bits En NOMMU, la memoria del espacio de usuario puede provenir de cualquier lugar de la RAM física. La definición actual de TASK_SIZE es incorrecta si existe RAM por encima de 4G, lo que provoca fallos falsos en las rutinas de acceso al espacio de usuario. • https://git.kernel.org/stable/c/6bd33e1ece528f67646db33bf97406b747dafda0 https://git.kernel.org/stable/c/04bf2e5f95c1a52e28a7567a507f926efe31c3b6 https://git.kernel.org/stable/c/52e8a42b11078d2aad4b9ba96503d77c7299168b https://git.kernel.org/stable/c/4201b8c8f2c32af321fb50867e68ac6c1cbed4be https://git.kernel.org/stable/c/a0f0dbbb1bc49fa0de18e92c36492ff6d804cdaa https://git.kernel.org/stable/c/efdcfa554b6eb228943ef1dd4d023c606be647d2 https://git.kernel.org/stable/c/6065e736f82c817c9a597a31ee67f0ce4628e948 https://lists.debian.org/debian-lts-announce/2024/06/ •
