The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3605-1 advisory.
An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)
An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. (CVE-2022-41674)
A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.x before 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code. (CVE-2022-42719)
Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after- free conditions to potentially execute code. (CVE-2022-42720)
A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in turn, potentially execute code. (CVE-2022-42721)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
