CVE-2026-84303

gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, the xDS RBAC HTTP filter in internal/xds/httpfilter/rbac/rbac.go does not lowercase header matcher names in normalizeHeaderMatcher even though incoming metadata keys are lowercase. A DENY policy using a mixed-case name such as...

CVE-2026-84304

gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, internal/transport/transport.go stores each fragmented HTTP/2 DATA frame as a separate recvMsg in recvBuffer, so millions of one-byte frames can consume disproportionate heap memory even when payload bytes remain within connectio...

CVE-2026-80574

In the Linux kernel, the following vulnerability has been resolved: Input: focaltech - fix array out-of-bounds in focaltechprocessrelpacket Make finger2 and also finger1 unsigned, so that if the finger index in the packet is 0 then subtracting 1 creates an array index which overflows above the...

CVE-2026-80573

CVE-2026-80544

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Improve EP11 CPRB domain handling with ASN.1 parsing The zcryptmsgtype6sendep11cprb function uses fragile struct overlays to access and modify the domain field in the EP11 CPRB payload, creating maintainability and...

CVE-2026-74741

In the Linux kernel, the following vulnerability has been resolved: net: ngbe: fix NULL pointer dereference in non-MSI-X interrupt enabling In non-MSI-X mode such as legacy INTx or single MSI, wx-msixentry is not allocated or initialized. Calling NGBEINTRMISCwx dereferences wx-msixentry-entry,...

PT-2026-82270

stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the broker s use of edge-triggered epoll EPOLLET and MSG PEEK in recv, causes sockets to enter a permanent half-read state. When enough such...

FreeBSD : FreeBSD -- Use-after-free in unix SOCK_STREAM message handling (e99e4b19-a0fd-11f1-ae1f-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the e99e4b19-a0fd-11f1-ae1f-bc241121aa0a advisory. The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages...

The vulnerability of the rxgk_do_verify_authenticator() function in the net/rxrpc/rxgk.c module allows attackers to compromise the confidentiality and accessibility of protected information, as it supports session sockets in the Linux operating system’s kernel.

The vulnerability of the rxgkdoverifyauthenticator function in the net/rxrpc/rxgk.c module relates to the execution of operations outside of the buffer in the memory of the Linux operating system’s kernel. Exploiting this vulnerability could allow an attacker to compromise the confidentiality and...
