CVE-2026-45949 hwrng: core - use RCU and work_struct to fix race condition

In the Linux kernel, the following vulnerability has been resolved: hwrng: core - use RCU and workstruct to fix race condition Currently, hwrngfill is not cleared until the hwrngfillfn thread exits. Since hwrngunregister reads hwrngfill outside the rngmutex lock, a concurrent hwrngunregister may...

CVE-2026-45949

CVE-2026-45949 details from connected OSV/NVD entries confirm a race in the Linux kernel hwrng core where concurrent unregister/start calls may cause use-after-free due to hwrng_fill not being cleared reliably.

CVE-2026-45927 bpf: Require frozen map for calculating map hash

In the Linux kernel, the following vulnerability has been resolved: bpf: Require frozen map for calculating map hash Currently, bpfmapgetinfobyfd calculates and caches the hash of the map regardless of the map's frozen state. This leads to a TOCTOU bug where userspace can call BPFOBJGETINFOBYFD t...

CVE-2026-45918 ovpn: tcp - don't deref NULL sk_socket member after tcp_close()

In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - don't deref NULL sksocket member after tcpclose When deleting a peer in case of keepalive expiration, the peer is removed from the OpenVPN hashtable and is temporary inserted in a "release list" for further processing...

CVE-2026-45918

CVE-2026-45918 concerns a race condition in the Linux kernel related to OpenVPN TCP handling. When a peer is kept alive and later removed, the kernel temporarily places the peer in a release list and detaches from the socket by restoring its proto and socket callbacks. If userspace closes the soc...

CVE-2026-45917 ipvs: do not keep dest_dst if dev is going down

In the Linux kernel, the following vulnerability has been resolved: ipvs: do not keep destdst if dev is going down There is race between the netdev notifier ipvsdstevent and the code that caches dst with dev that is going down. As the FIB can be notified for the closed device after our handler...
