Synopsis

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

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0759-1 advisory.

- In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. (CVE-2021-44879)

- Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

- Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

- A use-after-free vulnerability was found in rtsx_usb_ms_drv_remove in drivers/memstick/host/rtsx_usb_ms.c in memstick in the Linux kernel. In this flaw, a local attacker with a user privilege may impact system Confidentiality. This flaw affects kernel versions prior to 5.14 rc1. (CVE-2022-0487)

- A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
(CVE-2022-0492)

- A vulnerability was found in kvm_s390_guest_sida_op in the arch/s390/kvm/kvm-s390.c function in KVM for s390 in the Linux kernel. This flaw allows a local attacker with a normal user privilege to obtain unauthorized memory write access. This flaw affects Linux kernel versions prior to 5.17-rc4.
(CVE-2022-0516)

- A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

- A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

- An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)

- drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.
(CVE-2022-24958)

- An issue was discovered in the Linux kernel before 5.16.5. There is a memory leak in yam_siocdevprivate in drivers/net/hamradio/yam.c. (CVE-2022-24959)

- An issue was discovered in drivers/usb/gadget/composite.c in the Linux kernel before 5.16.10. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). Memory corruption might occur.
(CVE-2022-25258)

- An issue was discovered in drivers/usb/gadget/function/rndis.c in the Linux kernel before 5.16.10. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. Attackers can obtain sensitive information from kernel memory. (CVE-2022-25375)

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 packages.
