CVE-2024-36481

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rastreo/sondas: corrección de verificación de errores en parse_btf_field() btf_find_struct_member() puede devolver NULL o un error a través de la macro ERR_PTR(). Sin embargo, su llamador en parse_btf_field() solo verifica la condición NULL. Solucione este problema usando IS_ERR() y devolviendo el error en la pila.

In the Linux kernel, the following vulnerability has been resolved: tracing/probes: fix error check in parse_btf_field() btf_find_struct_member() might return NULL or an error via the ERR_PTR() macro. However, its caller in parse_btf_field() only checks for the NULL condition. Fix this by using IS_ERR() and returning the error up the stack.

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.
