CVE-2026-98856

The Linux kernel contains a vulnerability in the kprobes subsystem on x86 architectures. When arming a new probe (C) near an existing optkprobe (A), the get_optimized_kprobe() function incorrectly stops at a disarmed probe (B). This allows the INT3 instruction for probe C to overwrite the jump di...

CVE-2026-98856 kprobes: Skip disarmed probes when checking optkprobe overlap

In the Linux kernel, the following vulnerability has been resolved: kprobes: Skip disarmed probes when checking optkprobe overlap On x86, an optkprobe at A replaces five bytes with a jump. If a disabled probe B is at A+2, getoptimizedkprobe stops at B when arming a new probe C at A+4. It leaves A...
