- Summary
- CVE-2026-23285 affecting package kernel for versions less than 6.6.130.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drbd: fix null-pointer dereference on local read error
In drbdrequestendio(), READCOMPLETEDWITH_ERROR is passed to __reqmod() with a NULL peerdevice:
_reqmod(req, what, NULL, &m);
The READCOMPLETEDWITHERROR handler then unconditionally passes this NULL peerdevice to drbdsetoutofsync(), which dereferences it, causing a null-pointer dereference.
Fix this by obtaining the peerdevice via firstpeerdevice(device), matching how drbdreq_destroy() handles the same situation.
