CVE-2026-31518

CVE-2026-31518 affects the Linux kernel espintcp path when using asynchronous crypto. If the TX queue for espintcp is full, esp_output_tail_tcp returns an error and the skb is not freed under earlier synchronous handling; with async crypto (esp_output_done) the skb must be dropped when esp_output...

CVE-2026-31509

CVE-2026-31509 affects the Linux kernel NFC NCI subsystem. The vulnerability stems from nci_close_device() flushing rx_wq and tx_wq while holding req_lock, creating a circular locking dependency with nci_rx_work() and related paths. The fix moves the rx_wq flush to after req_lock is released, rel...

In the Linux kernel, the following vulnerability has been resolved: net: macb: use the current queue number for stats There's a potential mismatch between the memory reserved for statistics and the amount of memory written. gemgetssetcount correctly computes the number of stats based on the activ...

CVE-2026-31493

The CVE-2026-31493 issue exists in Linux kernel RDMA/efa admin queue completion handling: when a command completes with an error, the code may print from a completion context that has already been freed, leading to use-after-free-like behavior. The root cause is use of a freed completion context ...
