The vulnerability of the SOCK_STREAM component in the FreeBSD operating system allows a hacker to increase their privileges.

The vulnerability of the SOCKSTREAM component in FreeBSD operating systems relates to the possibility of exploiting memory after it is freed. Exploiting this vulnerability can allow an attacker to enhance their privileges...

CVE-2026-58090

The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this...

CVE-2026-58090 Use-after-free in unix SOCK_STREAM message handling

The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this...

CVE-2026-58090 Use-after-free in unix SOCK_STREAM message handling

The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this...

CVE-2026-58090

The SOCK_STREAM receive path in the FreeBSD unix socket implementation contains a use-after-free vulnerability. The flaw occurs because the system fails to fully detach control messages from the socket buffer before processing them; specific error paths free these messages while leaving freed dat...

CVE-2026-58090: Use After Free

The SOCKSTREAM receive path in the unix socket implementation failed to fully detach control messages from the socket buffer before processing them. Some error paths would free those messages, leaving freed data mbufs in the receive socket buffer. An unprivileged local user can exploit this...

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...

CVE-2024-50169

CVE-2024-50169 is a Linux kernel vulnerability in virtio_vsock/rx accounting. The connected Nessus entry confirms a concrete fix: after vtock read_skb(), the kernel now updates rx_bytes via virtio_transport_inc_rx_pkt() and virtio_transport_dec_rx_pkt() to keep rx_bytes in sync with dequeued pack...

CVE-2024-50169 vsock: Update rx_bytes on read_skb()

In the Linux kernel, the following vulnerability has been resolved: vsock: Update rxbytes on readskb Make sure virtiotransportincrxpkt and virtiotransportdecrxpkt calls are balanced i.e. virtiovsocksock::rxbytes doesn't lie after vsocktransport::readskb. While here, also inform the peer that we'v...

If such embryo has a peer that carries SCMRIGHTS, two consecutiv...

CVE-2024-26923

CVE-2024-26923 in the Linux kernel exposes a race in the AF_UNIX garbage collector during connect() handling. An embryo enqueued during GC may be reachable via a peer with SCM_RIGHTS, causing two consecutive scan passes to observe different child sets and inflate the inflight count, which can lea...

CVE-2021-47068

A flaw was found in the Linux kernel’s Near Field Communication NFC subsystem. The issue involves a use-after-free condition introduced by commits to fix reference count leaks. This vulnerability can be triggered if the same local address is assigned to two different sockets, leading to a potenti...
