**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability in the Linux kernel has been resolved, which caused a double SIGFPE crash on parisc. The issue occurred because glibc uses a double-word floating-point store to atomically update function descriptors, resulting in a floating-point store in fpe func almost immediately. When the T bit is set, an assist exception trap occurs when the co-processor encounters any floating-point instruction except for a double store of register %fr0. The issue can be reproduced with a test program. **Recommendations** To resolve the issue, clear the Trap (T) bit in the FP status register before returning to the signal handler in userspace. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
