  "details": "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, get_optimized_kprobe() stops at B when arming a new probe C at A+4. It leaves A optimized:                A    A+1  A+2  A+3  A+4   A's jump  | e9 | d0 | d1 | d2 | d3 |   after C   | e9 | d0 | d1 | d2 | cc |  The INT3 for C overwrites the last byte of A's jump displacement, so execution can jump to the wrong address. B can have prepared optinsns while disarmed, but has no jump to unoptimize.  Continue past disarmed and unprepared probes to find the active optimized probe before arming a probe in its jump.",
