CVE-2023-52735

Status: AnalyzedCritical (9.1)—
Severity9.1Critical · CVSS 3.1
Exploitation probability1.22 %higher than 68% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In the Linux kernel, the following vulnerability has been resolved:

bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself

sock_map proto callbacks should never call themselves by design. Protect against bugs like [1] and break out of the recursive loop to avoid a stack overflow in favor of a resource leak.
