CVE-2024-40902

In the Linux kernel, the following vulnerability has been resolved: jfs: xattr: fix buffer overflow for invalid xattr When an xattr size is not what is expected, it is printed out to the kernel log in hex format as a form of debugging. But when that xattr size is bigger than the expected size, printing it out can cause an access off the end of the buffer. Fix this all up by properly restricting the size of the debug hex dump in the kernel log.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: jfs: xattr: corrige el desbordamiento del búfer para xattr no válido Cuando un tamaño de xattr no es el esperado, se imprime en el registro del kernel en formato hexadecimal como una forma de depuración. Pero cuando el tamaño de xattr es mayor que el tamaño esperado, imprimirlo puede provocar un acceso desde el final del búfer. Solucione todo esto restringiendo adecuadamente el tamaño del volcado hexadecimal de depuración en el registro del kernel.
