A flaw was found in the Linux kernel. A local user could exploit a use-after-return vulnerability in the raid1_reshape function. This issue arises from improper handling of stack memory, where a pointer to a stack address is retained after the function returns. Subsequent access to this invalid memory address can lead to a kernel panic, causing a Denial of Service (DoS) on the system.
