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 •
