EUVD-2026-42312

Socket.IO enables bidirectional and low-latency communication for every platform. From 6.5.0 before 6.6.7, Engine.IO servers with WebTransport enabled can resolve a crafted session ID such as proto through an inherited property of the clients object during WebTransport upgrade handling, causing a...

CVE-2026-59724

Socket.IO’s Engine.IO component is affected in versions 6.5.0–6.6.6 when WebTransport is enabled. During a WebTransport upgrade, processing a crafted session ID such as proto on an inherited property of the clients object can trigger a TypeError, leading to a denial of service. The issue has been...

CVE-2026-59724 Socket.IO: Engine.IO WebTransport SID DoS

Socket.IO enables bidirectional and low-latency communication for every platform. From 6.5.0 before 6.6.7, Engine.IO servers with WebTransport enabled can resolve a crafted session ID such as proto through an inherited property of the clients object during WebTransport upgrade handling, causing a...

kernel: Bluetooth: SCO: Fix UAF on sco_sock_timeout

A use-after-free vulnerability was found in the Linux kernel's Bluetooth SCO. When scosocktimeout is called, conn-sk may be unlinked/freed while waiting for scoconnlock. This checks if the conn-sk is still valid by checking if it is part of scosklist, leading to a loss of availability and system...

kernel: Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix use-after-free bugs caused by scosocktimeout When the sco connection is established and then, the sco socket is releasing, timeoutwork will be scheduled to judge whether the sco disconnection is timeout. The sock...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

SUSE-SU-2026:22553-1 Security update for curl

This update for curl fixes the following issues - CVE-2026-8286: wrong STARTTLS connection reuse bsc1268402. - CVE-2026-8458: wrong reuse for different services bsc1268407. - CVE-2026-8924: traling dot domain super cookie bsc1268409. - CVE-2026-8927: env-set cross-proxy Digest auth state leak...

openssh: Local MITM of X11 forwarding via abstract UNIX socket pre-binding in Red Hat Enterprise Linux OpenSSH client versions

A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack ca...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: espintcp: fixed skb leaks. Several error paths now include a kfreeskb...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg – Zero initialize memory allocated via sockkmalloc Several crypto user API contexts and requests that were allocated using sockkmalloc remained uninitialized. This meant that callers had to explicitly set the fields...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the net: rose module, there is an issue where rosekillbydevice collects sockets into a local array, and then iterates over those arrays to disconnect sockets bound to devices that are being removed. The loop mistakenly indexes...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: 6lowpan: resetting the link-local header in the IPv6 receive path The Bluetooth 6lowpan.c netdev module has the headerops function; therefore, it must set the link-local header for the RX skb packet. Otherwise, thin...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: A narrower access to the pointer ctx fields was rejected. The following BPF program, simplified from a syzkaller repro, causes a kernel warning: c r0 = u8 r1 + 169; exit; Here, the pointer field sk is located at offset 168 i...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: wlcore – Ensure skbheadroom before calling skbpush. This fix prevents occasional skbunderpanic errors in wl1271txwork. In this case, the allocated headroom is less than what is actually needed typically 110 – 94 = 16 bytes...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: mptcp: Fixed the detection of protocol fallback using BPF. The sockmap feature allows for BPF syscall from user space, or based on BPF sockops, replacing the skprot of sockets during protocol stack processing with sockmap’s...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix memleak in nfcllcpsenduiframe. syzbot reported various memory leaks related to NFC, struct nfcllcpsock, skbuff, nfcdev, etc. 0 The leading log hinted that nfcllcpsenduiframe failed to allocate skb due to sockerrors...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mt76: mt7615: Fixed a memory leak in mt7615mcuwtblstaadd. In mt7615mcuwtblstaadd, an skb object named sskb is allocated. If the subsequent call to mt76connacmcuallocwtblreq fails, the function returns an error without freeing the...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bonding: A net pointer to skbflowdissect must be provided. After the code “net: plumb network namespace into skbflowdissect”, we need to provide a net pointer to skbflowdissect, either via skb-dev, skb-sk, or a user-provided...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: xfrm: esp: avoid in-place decrypt on shared skb frags The MSGSPLICEPAGES function can attach pages from a pipe directly to an skb. TCP marks such skbs with SKBFLSHAREDFRAG after skbsplicefromiter, so later processes that may modi...
