CVE-2026-98582

The Linux kernel contains a vulnerability in the nfc: st21nfca component. The function st21nfca_hci_i2c_repack() incorrectly trims a received frame at its EOF marker before removing byte stuffing, leading to an out-of-bounds read. Specifically, a malformed frame can cause the unstuffing loop to r...

CVE-2026-98581

The Linux kernel contains a vulnerability in the nfc: llcp component specifically within the nfc_llcp_recv_dm() function. The root cause is a list corruption and refcount desync occurring when handling DM(NOBOUND)/DM(REJ) for sockets still linked on local->connecting_sockets. Because the funct...

CVE-2026-98580

The Linux kernel contains a race condition in the nfc: llcp component related to the accept_queue lifecycle. Specifically, in nfc_llcp_socket_release(), the use of bh_lock_sock() fails to synchronize against the process-context lock_sock() held by nfc_llcp_accept_dequeue() during an accept operat...

CVE-2026-98579

The Linux kernel contains a memory leak vulnerability in the nfc: llcp component. Specifically, the function nfc_genl_llc_sdreq() fails to free queued TLV nodes during three specific error paths: nested-attr parse failure , TLV alloc ENOMEM , and nfc_llcp_send_snl_sdreq() failure . The issue is r...

CVE-2026-98578

The Linux kernel contains a vulnerability in the nfc: st21nfca component involving the ISO15693 inventory helper . The root cause is that the helper removes a two-byte prefix without verifying its existence and subsequently accepts a one-byte remainder before reading data as the DSFID . To remedi...
