The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through non-anonymous MEXTPG pages or...

CVE-2026-45257

CVE-2026-45257 : FreeBSD KTLS receive path decrypts in place, enabling an unprivileged local user to overwrite a file’s page cache via sendfile(2) data over a loopback connection when KTLS receive is enabled. This can corrupt the backing file and allow privilege escalation by overwriting setuid/t...

libnfs through 6.0.2 before 935b8db has an xid integer underflow in READIOVEC in rpcreadfromsocket in lib/socket.c during a connection to a crafted NFS server, when the expected pdu size exceeds the absolute pdu size from the xid/record-marker...

SUSE CVE-2026-40211

An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3 streams to trigger an out-of-memo...

libcurl 7.7 < 8.21.0 Incomplete mTLS Config Matching in Connection Reuse

The version of libcurl installed on the remote host is 7.7 prior to 8.21.0. It is, therefore, affected by an improper certificate validation vulnerability: - libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited...

libcurl 7.43.0 < 8.21.0 Wrong Negotiate Connection Reuse

The version of libcurl installed on the remote host is 7.43.0 prior to 8.21.0. It is, therefore, affected by an improper connection reuse vulnerability: - libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated ones, even when they are set to use...

CVE-2026-53072

A flaw was found in the Linux kernel's Bluetooth subsystem. Improper handling of locking within the hciconnrequestevt function, particularly when the HCIPROTODEFER protocol is active, can result in a Use-After-Free UAF vulnerability. This condition arises when a connection object is accessed afte...

kernel: nvmet-tcp: fix race between ICReq handling and queue teardown

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...

GHSA-VGWF-H737-FF37 golang.org/x/crypto: Invoking client can cause server deadlock on unexpected responses

A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close, resulting in a resource leak per connection. Unsolicited global responses are now discarded...

golang.org/x/crypto vulnerable to invoking bypass of certificate restrictions

When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError...
