Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference vulnerability has been resolved in the Linux kernel. The issue occurs when dummy codecs are declared, resulting in a zero-sized array. This causes the
dais[i].codecs pointer to point to the address of the next variable stored in the data section, leading to an out-of-bounds array reference. The vulnerability relies on the name member of the next variable being NULL, which is usually the case but can result in crashes when it is not. The fix involves checking dais.num codecs != 0 to prevent the dereference.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
