Description

A flaw was found in the Linux kernel's netfs component. Under certain circumstances, during a read retry operation, the system may incorrectly abandon subrequests. This issue arises because a pointer (`subreq`) used in the abandonment process can be uninitialized or point to invalid memory. An attacker could potentially exploit this to trigger a kernel oops, leading to a system crash and a Denial of Service (DoS).
