https://notcve.org/view.php?id=CVE-2023-52690
In the Linux kernel, the following vulnerability has been resolved: powerpc/powernv: Add a null pointer check to scom_debug_init_one() kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Add a null pointer check, and release 'ent' to avoid memory leaks. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: powerpc/powernv: agregue una verificación de puntero null a scom_debug_init_one() kasprintf() devuelve un puntero a la memoria asignada dinámicamente que puede ser NULL en caso de fallo. Agregue una verificación de puntero null y suelte 'ent' para evitar pérdidas de memoria. • https://git.kernel.org/stable/c/bfd2f0d49aef8abfe6bf58f12719f39912993cc6 https://git.kernel.org/stable/c/f84c1446daa552e9699da8d1f8375eac0f65edc7 https://git.kernel.org/stable/c/1eefa93faf69188540b08b024794fa90b1d82e8b https://git.kernel.org/stable/c/2a82c4439b903639e0a1f21990cd399fb0a49c19 https://git.kernel.org/stable/c/ed8d023cfa97b559db58c0e1afdd2eec7a83d8f2 https://git.kernel.org/stable/c/dd8422ff271c22058560832fc3006324ded895a9 https://git.kernel.org/stable/c/a9c05cbb6644a2103c75b6906e9dafb9981ebd13 https://git.kernel.org/stable/c/9a260f2dd827bbc82cc60eb4f4d8c2270 •

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 •
