In the Linux kernel, the following vulnerability has been resolved: ravb: Fixed the use-after-free issue in ravbtxtimeoutwork. The ravbstop function should call cancelworksync. Otherwise, ravbtxtimeoutwork may use the freed private data after ravbremove is called, as follows: CPU0 CPU1...

Linux Distros Unpatched Vulnerability : CVE-2026-80992

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: ravb: avoid dereferencing an invalid PTP clock The PTP clock is unavailable before the first open, so querying its index can dereference a NULL pointer...

Linux Distros Unpatched Vulnerability : CVE-2026-80991

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: ravb: serialize PTP clock teardown ravbptpinterrupt can race with ravbptpstop and pass the clock to ptpclockevent while ptpclockunregister is freeing it...

CVE-2026-80991

A flaw was found in the Linux kernel's net: ravb module. A race condition exists during the Precision Time Protocol PTP clock teardown. This allows the ravbptpinterrupt function to attempt to use a PTP clock after it has been freed by ptpclockunregister, leading to a use-after-free vulnerability...

CVE-2026-80992

A flaw was found in the net: ravb component of the Linux kernel. This vulnerability allows for a NULL pointer dereference when the Precision Time Protocol PTP clock's index is queried before it is properly initialized or if its registration fails. This issue could lead to a system crash, resultin...
