- -------------------------------------------------------------------------     Debian Security Advisory DSA-5739-1                   [email protected]     https://www.debian.org/security/                     Salvatore Bonaccorso     August 06, 2024                       https://www.debian.org/security/faq

Package        : wpa     CVE ID         : CVE-2024-5290

Rory McNamara reported a local privilege escalation in wpasupplicant: A     user able to escalate to the netdev group can load arbitrary shared     object files in the context of the wpa_supplicant process running as     root.

For the oldstable distribution (bullseye), this problem has been fixed     in version 2:2.9.0-21+deb11u2.

For the stable distribution (bookworm), this problem has been fixed in     version 2:2.10-12+deb12u2.

We recommend that you upgrade your wpa packages.

For the detailed security status of wpa please refer to its security     tracker page at:
https://security-tracker.debian.org/tracker/wpa
