Vulnerability from github – Published: 2025-04-16 15:34 – Updated: 2025-10-31 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

uprobes/x86: Harden uretprobe syscall trampoline check

Jann reported a possible issue when trampoline_check_ip returns address near the bottom of the address space that is allowed to call into the syscall if uretprobes are not set up:

Though the mmap minimum address restrictions will typically prevent creating mappings there, let's make sure uretprobe syscall checks for that.

Severity

5.5 (Medium)
