CVE-2024-42246: net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 02ee1976edb21a96ce8e3fd4ef563f14cc16d041, 5d8254e012996cee1a0f9cc920531cb7e4d9a011, 626dfed5fa3bfb41e0dffd796032b555b69f9cde; Azure Linux 3.0 ARM 6.6.43.1-7; Azure Linux 3.0 x64 6.6.43.1-7.

Low priority for now. Upgrade to Linux Linux 02ee1976edb21a96ce8e3fd4ef563f14cc16d041, 5d8254e012996cee1a0f9cc920531cb7e4d9a011, 626dfed5fa3bfb41e0dffd796032b555b69f9cde; Azure Linux 3.0 ARM 6.6.43.1-7; Azure Linux 3.0 x64 6.6.43.1-7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket When using a BPF program on kernel_connect(), the call can return -EPERM. This causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing the kernel to potentially freeze up. Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN. ECONNREFUSED as error seems reasonable. For programs setting a different error can be out of reach (see handling in 4fbac77d2d09) in particular on kernels which do not have f10d05966196 ("bpf: Make BPF_PROG_RUN_ARRAY return -err instead of allow boolean"), thus given that it is better to simply remap for consistent behavior. UDP does handle EPERM in xs_udp_send_request().
