CVE-2026-90335 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
tty: skip cdev_del() when no cdev is registered
TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdev_del(), causing a NULL-pointer dereference.
Only delete the cdev when the slot is not NULL.
