Ubuntu 22.04 LTS : Linux kernel vulnerabilities (USN-6024-1)

high Nessus Plugin ID 174449

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-6024-1 advisory.

 - A use-after-free flaw was found in the Linux kernel's SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-3424)

 - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

 - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in net/sched/sch_api.c. (CVE-2022-47929)

 - A use-after-free flaw was found in io_uring/poll.c in io_poll_check_events in the io_uring subcomponent in the Linux Kernel due to a race condition of poll_refs. This flaw may cause a NULL pointer dereference.
 (CVE-2023-0468)

 - The Linux kernel io_uring IORING_OP_SOCKET operation contained a double free in function
 __sys_socket_file() in file net/socket.c. This issue was introduced in da214a475f8bd1d3e9e7a19ddfeb4d1617551bab and fixed in 649c15c7691e9b13cbe9bf6c65c365350e056067.
 (CVE-2023-1032)

 - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use- after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

 - In the Linux kernel before 6.1.2, kernel/module/decompress.c misinterprets the module_get_next_page return value (expects it to be NULL in the error case, whereas it is actually an error pointer). (CVE-2023-22997)

 - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

 - In the Linux kernel 6.0.8, there is a use-after-free in ntfs_trim_fs in fs/ntfs3/bitmap.c.
 (CVE-2023-26606)

 - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. The message from user space is not checked properly before transferring into the device.
 This flaw allows a local user to crash the system or potentially cause a denial of service.
 (CVE-2023-28328)

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.
