libcurl 8.13.0 < 8.21.0 Use-After-Free in Socket Callback

The version of libcurl installed on the remote host is 8.13.0 prior to 8.21.0. It is, therefore, affected by a use-after-free vulnerability: - Calling curleasypause within the event-based CURLMOPTSOCKETFUNCTION callback triggers a use-after-free vulnerability. CVE-2026-9080 Note that Nessus has n...

golang.org/x/crypto is vulnerable to invoking server panic during CheckHostKey/Authenticate flow

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil...

CVE-2026-53115

A flaw was found in the Linux kernel's fsl-mc bus driver. During the driver probing process, a Use-After-Free UAF vulnerability can occur because the match callback accesses the driveroverride field without proper locking. This can lead to system instability or potentially allow an attacker to...

curl: UAF read in mev_pollset_diff() trace path after curl_easy_pause() in socket callback

Summary: The CVE-2026-9080 fix re-fetches the shentry after the socket callback inside mevshentryupdate, because curleasypause called from that callback re-enters mevassess and can free the entry. The same re-fetch was not applied at the caller, mevpollsetdiff, which dereferences its own entry...
