Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 35 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2022-b948fc3cfb advisory.

 - A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)

 - drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.
 (CVE-2022-40768)

 - 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)

 - In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices. (CVE-2022-42722)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
