CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52679 – of: Fix double free in of_parse_phandle_with_args_map
https://notcve.org/view.php?id=CVE-2023-52679
In the Linux kernel, the following vulnerability has been resolved: of: Fix double free in of_parse_phandle_with_args_map In of_parse_phandle_with_args_map() the inner loop that iterates through the map entries calls of_node_put(new) to free the reference acquired by the previous iteration of the inner loop. This assumes that the value of "new" is NULL on the first iteration of the inner loop. Make sure that this is true in all iterations of the outer loop by setting "new" to NULL after its value is assigned to "cur". Extend the unittest to detect the double free and add an additional test case that actually triggers this path. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: of: Solucionado double free en of_parse_phandle_with_args_map En of_parse_phandle_with_args_map() el bucle interno que itera por las entradas del mapa llama a of_node_put(new) para liberar la referencia adquirida por la iteración anterior del bucle interno . Esto supone que el valor de "nuevo" es NULL en la primera iteración del bucle interno. Asegúrese de que esto sea cierto en todas las iteraciones del bucle externo estableciendo "nuevo" en NULL después de que su valor se asigne a "cur". • https://git.kernel.org/stable/c/bd6f2fd5a1d52198468c5cdc3c2472362dff5aaa https://git.kernel.org/stable/c/26b4d702c44f9e5cf3c5c001ae619a4a001889db https://git.kernel.org/stable/c/a0a061151a6200c13149dbcdb6c065203c8425d2 https://git.kernel.org/stable/c/d5f490343c77e6708b6c4aa7dbbfbcbb9546adea https://git.kernel.org/stable/c/4541004084527ce9e95a818ebbc4e6b293ffca21 https://git.kernel.org/stable/c/b9d760dae5b10e73369b769073525acd7b3be2bd https://git.kernel.org/stable/c/b64d09a4e8596f76d27f4b4a90a1cf6baf6a82f8 https://git.kernel.org/stable/c/cafa992134124e785609a406da4ff2b54 •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2023-52676 – bpf: Guard stack limits against 32bit overflow
https://notcve.org/view.php?id=CVE-2023-52676
In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset. The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset either comes from an instruction (in which case it is 16 bit), from another register (in which case the caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being up to an u32, it appears that we were open to overflowing the `int`s which were currently used for arithmetic.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a double-free in arfs_create_groups When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net/mlx5e: corregido un double free en arfs_create_groups Cuando falla `in` asignado por kvzalloc, arfs_create_groups liberará ft->g y devolverá un error. Sin embargo, arfs_create_table, el único llamador de arfs_create_groups, mantendrá este error y llamará a mlx5e_destroy_flow_table, en el que ft->g se liberará nuevamente.
