QEMU: Denial of Service via Improper Synchronization in QEMU NBD Server During Socket Closure
A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service DoS attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline...
kernel: tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets
In the Linux kernel, the following vulnerability has been resolved: tcp: defer shutdownSENDSHUTDOWN for TCPSYNRECV sockets TCPSYNRECV state is really special, it is only used by cross-syn connections, mostly used by fuzzers. In the following crash 1, syzbot managed to trigger a divide by zero in...
kernel: mptcp: fix double-free on socket dismantle
In the Linux kernel, the following vulnerability has been resolved: mptcp: fix double-free on socket dismantle when MPTCP server accepts an incoming connection, it clones its listener socket. However, the pointer to 'inetopt' for the new socket has the same value as the original one: as a...
kernel: net: usb: lan78xx: Limit packet length to skb->len
In the Linux kernel, the following vulnerability has been resolved: net: usb: lan78xx: Limit packet length to skb-len Packet length retrieved from descriptor may be larger than the actual socket buffer length. In such case the cloned skb passed up the network stack will leak kernel memory content...
kernel: net/iucv: fix use after free in iucv_sock_close()
A possible use-after-free vulnerability was found in the Linux kernel in iucvsockclose. This issue may lead to a crash or memory corruption...
kernel: inet: read sk->sk_family once in inet_recv_error()
In the Linux kernel, the following vulnerability has been resolved: inet: read sk-skfamily once in inetrecverror inetrecverror is called without holding the socket lock. IPv6 socket could mutate to IPv4 with IPV6ADDRFORM socket option and trigger a KCSAN warning...
kernel: can: j1939: Fix UAF in j1939_sk_match_filter during setsockopt(SO_J1939_FILTER)
In the Linux kernel, the following vulnerability has been resolved: can: j1939: Fix UAF in j1939skmatchfilter during setsockoptSOJ1939FILTER Lock jsk-sk to prevent UAF when setsockopt..., SOJ1939FILTER, ... modifies jsk-filters while receiving packets. Following trace was seen on affected system:...
kernel: atl1c: Work around the DMA RX overflow issue
In the Linux kernel, the following vulnerability has been resolved: atl1c: Work around the DMA RX overflow issue This is based on alx driver commit 881d0327db37 "net: alx: Work around the DMA RX overflow issue". The alx and atl1c drivers had RX overflow error which was why a custom allocator was...
kernel: Bluetooth: ISO: Check socket flag instead of hcon
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Check socket flag instead of hcon This fixes the following Smatch static checker warning: net/bluetooth/iso.c:1364 isosockrecvmsg error: we previously assumed 'pi-conn-hcon' could be null line 1359...
kernel: geneve: make sure to pull inner header in geneve_rx()
In the Linux kernel, the following vulnerability has been resolved: geneve: make sure to pull inner header in geneverx syzbot triggered a bug in geneverx 1 Issue is similar to the one I fixed in commit 8d975c15c0cd "ip6tunnel: make sure to pull inner header in ip6tnlrcv" We have to save...
kernel: inet: inet_defrag: prevent sk release while still in use
In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use iplocalout and other functions can pass skb-sk as function argument. If the skb is a fragment and reassembly happens before such function call returns, the sk must not be...
kernel: tls: get psock ref after taking rxlock to avoid leak
In the Linux kernel, the following vulnerability has been resolved: tls: get psock ref after taking rxlock to avoid leak At the start of tlsswrecvmsg, we take a reference on the psock, and then call tlsrxreaderlock. If that fails, we return directly without releasing the reference. Instead of...
kernel: erspan: make sure erspan_base_hdr is present in skb->head
In the Linux kernel, the following vulnerability has been resolved: erspan: make sure erspanbasehdr is present in skb-head The Linux kernel CVE team has assigned CVE-2024-35888 to this issue. Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024051947-CVE-2024-35888-1e04@gregkh/T...
libvirt: Crash of virtinterfaced via virConnectListInterfaces()
A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterface...
PT-2025-18832
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A issue in the Linux kernel has been identified where the packet length retrieved from a descriptor may be larger than the actual socket buffer length, leading to a leak of kernel memory...
Denial Of Service (DoS)
Waitress is vulnerable to Denial Of Service DoS. The vulnerability is due to a race condition where, if a remote client closes the connection before Waitress calls getpeername, allows an attacker to trigger a busy-loop in the server, causing it to repeatedly attempt writing to a non-existent sock...
