libcurl 8.13.0 < 8.21.0 Use-After-Free in Socket Callback

The version of libcurl installed on the remote host is 8.13.0 prior to 8.21.0. It is, therefore, affected by a use-after-free vulnerability: - Calling curleasypause within the event-based CURLMOPTSOCKETFUNCTION callback triggers a use-after-free vulnerability. CVE-2026-9080 Note that Nessus has n...

PT-2026-52694

Name of the Vulnerable Software and Affected Versions libnfs versions prior to 6.0.2 Description An integer underflow occurs in the READ IOVEC section of the rpc read from socket function within lib/socket.c. This issue is triggered during a connection to a crafted NFS server when the expected PD...

Name of the Vulnerable Software and Affected Versions Kestra versions prior to 1.0.45 Kestra versions prior to 1.3.21 Description The authentication filter for the REST API endpoint /api/v1/ incorrectly treats any request path ending in /configs as a public instance-config endpoint, allowing it t...

CVE-2026-53184

A flaw was found in the Linux kernel. When a User Datagram Protocol UDP socket is configured with a sockmap, and a BPF Berkeley Packet Filter program attached to it calls a socket-lookup helper, the skb-dev field is not properly cleared. This improper handling of the skb-dev field can lead to a...

CVE-2026-53005

A flaw was found in the Linux kernel's afunix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message SCM attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may...

kernel: tcp: fix potential race in tcp_v6_syn_recv_sock()

A flaw was found in the Linux kernel. A race condition exists in the TCP Transmission Control Protocol IPv6 Internet Protocol version 6 socket handling, specifically within the tcpv6synrecvsock function. This occurs because a child socket becomes visible in the TCP hash table before its...

CVE-2026-52993

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

CVE-2026-53009

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

curl: UAF read in mev_pollset_diff() trace path after curl_easy_pause() in socket callback

Summary: The CVE-2026-9080 fix re-fetches the shentry after the socket callback inside mevshentryupdate, because curleasypause called from that callback re-enters mevassess and can free the entry. The same re-fetch was not applied at the caller, mevpollsetdiff, which dereferences its own entry...

EUVD-2026-39337

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential unbounded skb queue virtiotransportincrxpkt checks vvs-rxbytes + len vvs-bufalloc. virtiotransportrecvenqueue skips coalescing for packets with VIRTIOVSOCKSEQEOM. If fed with packets with len == 0 and...

CVE-2026-53276

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix a use-after-free of the hciconn pointer In isosockrebindbc, the bis pointer is cached, then the socket lock is dropped: bis = isopisk-conn-hcon; / Release the socket before lookups since that requires hcidevlo...

CVE-2026-53253

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and setup UUID-size byte before...

CVE-2026-53236

In the Linux kernel, the following vulnerability has been resolved: tcp: restrict SOATTACHFILTER to priv users This patch restricts the use of SOATTACHFILTER cBPF on TCP sockets to users with CAPNETADMIN capability. This blocks potential side-channel attack where an unprivileged application...

CVE-2026-53227

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix possible kfreeskb of ERRPTR After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovsmutex. However, error cleanups still follow the classical...

CVE-2026-53215

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53151

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in rxrpcinputsoftacks and a potential incorrect access of the buffer in a fragmented UDP packet the packet would probably hav...
