AlmaLinux 9 : kernel (ALSA-2023:0951)

high Nessus Plugin ID 172003

Synopsis

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

Description

The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:0951 advisory.

 - An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)

 - A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

 - A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4378)

 - A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
 This flaw allows an attacker to conduct a remote denial (CVE-2022-4379)

 - kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan (CVE-2023-0179)

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.
