A flaw was found in the zram component of the Linux kernel. This vulnerability occurs because the system does not properly validate user-supplied deflate parameters, specifically winbits values. An attacker could exploit this by providing malformed input, which would trigger an internal error (BUG_ON()) and lead to a system crash, resulting in a Denial of Service (DoS).
