CVE-2026-89725

CVE-2026-89725 affects the Linux kernel's media: cec: stm32 driver, where stm32_rx_done() writes received CEC bytes into a fixed 16-byte buffer (rx_msg.msg[]) without bounds-checking the write index. A remote CEC device on an adjacent network that transmits bytes without an end-of-message signal ...

CVE-2026-80979

CVE-2026-80979 is a use-after-free in the Linux kernel's Shared Memory Communications (SMC) component (net/smc). During connection termination, a race between smc_conn_free() and smc_lgr_terminate_sched() allows the device to re-arm the receive tasklet after tasklet_kill() returns. On the DMB-noc...

CVE-2026-80951

CVE-2026-80951 is an out-of-bounds write in the Linux kernel's i3c master svc driver. The function svc_i3c_master_handle_ibi() reads IBI payloads from the RX FIFO, but its loop is bounded by the hardware FIFO size rather than the per-slot max_payload_len . When a device sends more bytes than the ...

In the Linux kernel, the following vulnerability has been resolved: media: cec: stm32: prevent out-of-bounds write on RX overflow stm32 rx done appends each received CEC byte to rx msg.msg using rx msg.len as the write index, incrementing it on every RXBR receive-byte-ready interrupt without...

kernel: wifi: mac80211: capture fast-RX rate before mesh reuses skb->cb

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This use-after-free vulnerability arises from incorrect handling of fast-RX rate data during mesh processing. This can lead to memory corruption, which an attacker could potentially exploit to cause a system crash denial of service...

CVE-2026-80779

CVE-2026-80779 is a Linux kernel vulnerability in the net/ionic network driver. The dedicated hardware timestamp RX queue is allocated with an index equal to nrxqs_per_lif , but the txqcqs array only holds regular queue pairs. Using that out-of-bounds index to set rxq->partner can read one ent...
