A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
