grafana: Grafana: Denial of Service due to excessive memory allocation via large JSON payloads

A flaw was found in Grafana. An unauthenticated attacker can exploit the public dashboard query endpoint by sending arbitrarily large JSON payloads. This vulnerability, caused by a lack of request body size limits, triggers excessive memory allocation, leading to a denial of service through memor...

Cesanta Mongoose before 7.22 contains an out-of-bounds read in the built-in TLS server function mgtlsserverrecvhello, which uses an attacker-controlled sessionidlen byte from a TLS ClientHello as a buffer index without validating it against the length of received data. A remote, unauthenticated...

CVE-2026-12234

The userspace syscall verifiers zvrfyzsocksendmsg and zvrfyzsockrecvmsg in subsys/net/lib/sockets/sockets.c snapshot the caller-supplied struct netmsghdr into a kernel-side copy with kusermodefromcopy, but then re-read the still-live user struct for subsequent decisions. The kernel iovec shadow...

CVE-2026-12233

The PSA Protected Storage credential backend subsys/net/lib/tlscredentials/tlscredentialstrusted.c declared its credential-store mutex as a plain zero-filled static struct kmutex credentiallock; and never called kmutexinit on it. A statically zero-filled kmutex has an uninitialized wait queue its...

CVE-2026-12234 TOCTOU double-fetch in `zsock_sendmsg`/`recvmsg` userspace verifiers allows kernel-heap out-of-bounds write

The userspace syscall verifiers zvrfyzsocksendmsg and zvrfyzsockrecvmsg in subsys/net/lib/sockets/sockets.c snapshot the caller-supplied struct netmsghdr into a kernel-side copy with kusermodefromcopy, but then re-read the still-live user struct for subsequent decisions. The kernel iovec shadow...

CVE-2026-12233

CVE-2026-12233 affects the PSA Protected Storage TLS credential backend. The credential_store mutex was declared as a zero-initialized static k_mutex and never initialized, leaving its wait queue NULL. Under contention, z_pend_curr() appends to this uninitialized wait queue and dereferences a NUL...

CVE-2026-12233 Uninitialized mutex in TLS trusted-credential backend causes kernel NULL-deref DoS under contention

CVE-2026-12232 Out-of-bounds read via unvalidated stream_id in Intel ALH DAI get_properties

The Intel ALH digital-audio-interface driver function daialhgetproperties in drivers/dai/intel/alh/alh.c used a caller-supplied int streamid with no range validation. The value indexes the fixed-size static const uint8t alhhandshakemap64 array and scales a FIFO register address, so an out-of-rang...
