https://notcve.org/view.php?id=CVE-2023-52804
In the Linux kernel, the following vulnerability has been resolved: fs/jfs: Add validity check for db_maxag and db_agpref Both db_maxag and db_agpref are used as the index of the db_agfree array, but there is currently no validity check for db_maxag and db_agpref, which can lead to errors. The following is related bug reported by Syzbot: UBSAN: array-index-out-of-bounds in fs/jfs/jfs_dmap.c:639:20 index 7936 is out of range for type 'atomic_t[128]' Add checking that the values of db_maxag and db_agpref are valid indexes for the db_agfree array. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fs/jfs: agregue verificación de validez para db_maxag y db_agpref. Tanto db_maxag como db_agpref se utilizan como índice de la matriz db_agfree, pero actualmente no hay verificación de validez para db_maxag y db_agpref, lo cual puede dar lugar a errores. El siguiente es un error relacionado reportado por Syzbot: UBSAN: array-index-out-of-bounds in fs/jfs/jfs_dmap.c:639:20 el índice 7936 está fuera de rango para el tipo 'atomic_t[128]' Agregue verificando que el Los valores de db_maxag y db_agpref son índices válidos para la matriz db_agfree. • https://git.kernel.org/stable/c/a0649e2dd4a3595b5595a29d0064d047c2fae2fb https://git.kernel.org/stable/c/ce15b0f1a431168f07b1cc6c9f71206a2db5c809 https://git.kernel.org/stable/c/32bd8f1cbcf8b663e29dd1f908ba3a129541a11b https://git.kernel.org/stable/c/c6c8863fb3f57700ab583d875adda04caaf2278a https://git.kernel.org/stable/c/1f74d336990f37703a8eee77153463d65b67f70e https://git.kernel.org/stable/c/5013f8269887642cca784adc8db9b5f0b771533f https://git.kernel.org/stable/c/dca403bb035a565bb98ecc1dda5d30f676feda40 https://git.kernel.org/stable/c/2323de34a3ae61a9f9b544c18583f71ce •

https://notcve.org/view.php?id=CVE-2023-52799
In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbFindLeaf Currently while searching for dmtree_t for sufficient free blocks there is an array out of bounds while getting element in tp->dm_stree. To add the required check for out of bound we first need to determine the type of dmtree. Thus added an extra parameter to dbFindLeaf so that the type of tree can be determined and the required check can be applied. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: jfs: corrige el índice de matriz fuera de los límites en dbFindLeaf. Actualmente, mientras se busca dmtree_t para suficientes bloques libres, hay una matriz fuera de los límites al obtener el elemento en tp->dm_stree . • https://git.kernel.org/stable/c/20f9310a18e3e99fc031e036fcbed67105ae1859 https://git.kernel.org/stable/c/86df90f3fea7c5591f05c8a0010871d435e83046 https://git.kernel.org/stable/c/ecfb47f13b08b02cf28b7b50d4941eefa21954d2 https://git.kernel.org/stable/c/81aa58cd8495b8c3b527f58ccbe19478d8087f61 https://git.kernel.org/stable/c/da3da5e1e6f71c21d8e6149d7076d936ef5d4cb9 https://git.kernel.org/stable/c/a50b796d36719757526ee094c703378895ab5e67 https://git.kernel.org/stable/c/88b7894a8f8705bf4e7ea90b10229376abf14514 https://git.kernel.org/stable/c/87c681ab49e99039ff2dd3e7185241738 •

In the Linux kernel, the following vulnerability has been resolved: media: gspca: cpia1: shift-out-of-bounds in set_flicker Syzkaller reported the following issue: UBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27 shift exponent 245 is too large for 32-bit type 'int' When the value of the variable "sd->params.exposure.gain" exceeds the number of bits in an integer, a shift-out-of-bounds error is reported. It is triggered because the variable "currentexp" cannot be left-shifted by more than the number of bits in an integer. In order to avoid invalid range during left-shift, the conditional expression is added.
