CVE-2026-80990

CVE-2026-80990 is a resource-leak bug in the Linux kernel Thunderbolt networking (tbnet ) subsystem. In tbnet_connected_work(), the function requests a specific Rx HopID from tb_xdomain_alloc_in_hopid(), which uses ida_alloc_range() with the desired ID as a lower bound. If the requested ID is alr...

CVE-2026-80990 net: thunderbolt: Release the Rx HopID that was handed out on mismatch

In the Linux kernel, the following vulnerability has been resolved: net: thunderbolt: Release the Rx HopID that was handed out on mismatch tbxdomainallocinhopid passes the wanted HopID to idaallocrange as the lower bound, so a taken id is not an error there: the allocator returns the next free on...

CVE-2026-80982

CVE-2026-80982 is a use-after-free in the Linux kernel's SMC (Shared Memory Communications) network protocol (net/smc). The root cause is a race condition in smc_rx_pipe_buf_release(): it checks sk_state before acquiring the socket lock, so a concurrent smc_conn_free() can release the connection ...

CVE-2026-80980 net/smc: stop killed, freed and out_of_sync sharing a byte

In the Linux kernel, the following vulnerability has been resolved: net/smc: stop killed, freed and outofsync sharing a byte The three connection state flags are single-bit bitfields, so they occupy one byte of struct smcconnection and every store to one is a read-modify-write of the other two: u...

CVE-2026-80980

CVE-2026-80980 is a race condition in the Linux kernel's SMC (Server Message Block over Remote Direct Memory Access) protocol. Three single-bit flags (killed, freed, out_of_sync) in struct smc_connection share a single byte and are written from concurrent contexts—smc_cdc_msg_validate() from a re...
