Ubuntu 25.04 : Linux kernel (Azure) vulnerabilities (USN-7721-1)

"The remote Ubuntu 25.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7721-1 advisory. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in th...

The vulnerability of the function ieee80211_vif_use_reserved_context() in the module net/mac80211/chan.c of the Linux kernel’s mac80211 stack allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the function ieee80211vifusereservedcontext in the net/mac80211/chan.c module of the mac80211 stack in the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentialit...

CVE-2025-38642

CVE-2025-38642 affects the Linux kernel’s wifi/mac80211 monitor mode handling. The issue arises on devices without WANT_MONITOR_VIF (and likely without channel context support), triggering a WARN_ON when modifying the per-link settings of a MONITOR interface. The fix moves this validation from a ...
