CVE-2023-53133 bpf, sockmap: Fix an infinite loop error when len is 0 in tcp_bpf_recvmsg_parser()

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix an infinite loop error when len is 0 in tcpbpfrecvmsgparser When the buffer length of the recvmsg system call is 0, we got the flollowing soft lockup problem: watchdog: BUG: soft lockup - CPU3 stuck for 27s!...

CVE-2023-53133

CVE-2023-53133 affects the Linux kernel’s BPF sockmap path (tcp_bpf_recvmsg_parser) where a 0-length recvmsg can loop indefinitely. The description and connected advisories confirm the root cause is an infinite loop when len is 0 and that the fix is to return 0 for length 0 in tcp_bpf_recvmsg_par...

UBUNTU-CVE-2024-53122

In the Linux kernel, the following vulnerability has been resolved: mptcp: cope racing subflow creation in mptcprcvspaceadjust Additional active subflows - i.e. created by the in kernel path manager - are included into the subflow list before starting the 3whs. A racing recvmsg spooling data...

CVE-2024-53122

CVE-2024-53122 affects the Linux kernel mptcp subsystem. A race during subflow creation in mptcp_rcv_space_adjust could cause a racing recvmsg() to trigger tcp_cleanup_rbuf() on all current subflows, potentially leading to a divide-by-zero in newly created subflows. The fix explicitly checks subf...

The vulnerability of the tls component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the tls component in the Linux operating system’s kernel is related to improper blocking of resources in the tlsswrecvmsg function. Exploiting this vulnerability can allow an attacker to cause a service failure...

SUSE CVE-2024-44996

In the Linux kernel, the following vulnerability has been resolved: vsock: fix recursive -recvmsg calls After a vsock socket has been added to a BPF sockmap, its prot-recvmsg has been replaced with vsockbpfrecvmsg. Thus the following recursiion could happen: vsockbpfrecvmsg - vsockrecvmsg -...

CVE-2024-44996

A vulnerability was found in the Linux kernel related to vsock, involving recursive calls due to BPF sockmap integration. When a vsock socket was added to a BPF sockmap, the prot-recvmsg function was replaced with vsockbpfrecvmsg. This could lead to recursion as vsockbpfrecvmsg called vsockrecvms...
