EUVD-2026-55429

In the Linux kernel, the following vulnerability has been resolved: nfp: Check resource mutex allocation nfpcppresourcefind allocates a CPP mutex handle for the matching resource-table entry and then reports success. nfpresourcetryacquire immediately passes that handle to nfpcppmutextrylock...

CVE-2026-68328

The CVE relates to the Linux kernel nfp subsystem. Specifically, nfp_cpp_resource_find() allocates a CPP mutex handle for a matching resource-table entry, and nfp_resource_try_acquire() passes that handle to nfp_cpp_mutex_trylock(). If nfp_cpp_mutex_alloc() fails and returns NULL, the resource lo...

CVE-2026-68313

The CVE-2026-68313 entry concerns a Linux kernel tipc issue where a negative return from the cmd->dumpit callback could cause an infinite loop in the __tipc_nl_compat_dumpit code path, because the while (len) loop never terminates and the genl_mutex is not released. The vulnerability is resolv...

EUVD-2026-55289

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: Fix session UAF in settermios rfcommttysettermios tests dlc-session without rfcommmutex and later passes the pointer to rfcommsendrpn. The latter dereferences both session-initiator and session-sock. Meanwhile,...

CVE-2026-68188

CVE-2026-68188 : In the Linux kernel Bluetooth RFCOMM path, a race caused use-after-free in rfcomm_send_rpn when rfcomm_tty_set_termios tests dlc->session without holding rfcomm_mutex and the DLC/session is freed by krfcommd. The fix adds rfcomm_dlc_send_rpn() that holds rfcomm_mutex while ver...

CVE-2026-68179 misc: nsm: only unlock nsm_dev on post-lock error paths

In the Linux kernel, the following vulnerability has been resolved: misc: nsm: only unlock nsmdev on post-lock error paths nsmdevioctl jumps to the common out label even when the initial copyfromuser fails before nsm-lock has been taken. The error path then blindly unlocks a mutex that was never...

CVE-2026-68179

CVE-2026-68179 affects the Linux kernel NSM: nsm_dev_ioctl() may unlock a mutex that was never acquired when pre-lock copy_from_user() fails, risking a local DoS. A patch changes control flow to return immediately on pre-lock failures and to keep the unlock path for post-lock errors only. The vul...

CVE-2026-68146

The CVE-2026-68146 entry documents a Linux kernel ftrace vulnerability where the trace_parser state (idx, cont, buffer) could race when multiple threads share an open trace file descriptor and perform concurrent writes or releases. The fix introduces a global mutex (parser_lock) to serialize all ...
