high Nessus Plugin ID 161958

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5471-1 advisory.

 - A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. (CVE-2022-1012)

 - A NULL pointer dereference flaw was found in the Linux kernel's Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.
 (CVE-2022-1205)

 - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write when non synchronized between cleanup routine and firmware download routine.
 (CVE-2022-1734)

 - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
 An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

 - An issue was discovered in the Linux kernel through 5.17.5. io_rw_init_file in fs/io_uring.c lacks initialization of kiocb->private. (CVE-2022-29968)

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.
