From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - The description states: "tick/broadcast: Move per CPU pointer access into the atomic section". - This vulnerability relates to tick/broadcast and involves moving CPU pointer access into an atomic section. 2. Fix Content: - The fix involves moving CPU pointer access into an atomic section. - This ensures that the CPU pointer retrieved in a preemption context is more reliable. 3. Reason for Fix: - The reason for the fix is that the compiler moved the access into a non-preemptible region, while the pointer is actually used in that region. - The issue was resolved by moving the access into the actual non-preemptible region where it is used. 4. Fix Code: - The fix is located in the file . - It modifies the code in the function. 5. Fix Status: - The fix has been committed to the kernel code repository. - The commit ID is . 6. Fixer: - The fixer is Thomas Gleixner, with commit ID . 7. Commit Time: - The commit time is July 31, 2024. 8. Fix Description: - The fix description notes that recent changes made the broadcast timer takeover more reliable, but the compiler moved the access into a non-preemptible region, causing the access to be retained in the region where it is actually used. - This issue was resolved by moving the access into the actual non-preemptible region where it is used. 9. Fix Link: - The fix link is . With this information, we can understand the fix process, content, and key details such as the fixer and commit time.
