The version of kernel installed on the remote host is prior to 5.15.148-97.158. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2024-036 advisory.
2024-06-06: CVE-2023-52698 was added to this advisory.
2024-05-09: CVE-2024-26586 was added to this advisory.
2024-04-25: CVE-2023-52462 was added to this advisory.
2024-04-25: CVE-2024-26591 was added to this advisory.
2024-04-25: CVE-2023-52467 was added to this advisory.
2024-03-27: CVE-2023-52439 was added to this advisory.
2024-03-13: CVE-2023-52463 was added to this advisory.
2024-02-15: CVE-2024-1085 was added to this advisory.
A flaw has been found in Xen. An unprivileged guest can cause Denial of Service (DoS) of the host by sending network packets to the backend, causing the backend to crash. (CVE-2023-46838)
In the Linux kernel, the following vulnerability has been resolved:
uio: Fix use-after-free in uio_open
core-1 core-2------------------------------------------------------- uio_unregister_device uio_openidev = idr_find()device_unregister(&idev->dev)put_device(&idev- >dev)uio_device_releaseget_device(&idev->dev)kfree(idev)uio_free_minor(minor)uio_releaseput_device(&idev- >dev)kfree(idev)-------------------------------------------------------
In the core-1 uio_unregister_device(), the device_unregister will kfreeidev when the idev->dev kobject ref is 1. But after core-1device_unregister, put_device and before doing kfree, the core-2 mayget_device.
Then:1. After core-1 kfree idev, the core-2 will do use-after-free for idev.2. When core-2 do uio_release and put_device, the idev will be doublefreed.
To address this issue, we can get idev atomic & inc idev reference withminor_lock. (CVE-2023-52439)
In the Linux kernel, the following vulnerability has been resolved:
bpf: fix check for attempt to corrupt spilled pointer (CVE-2023-52462)
In the Linux kernel, the following vulnerability has been resolved: efivarfs: force RO when remounting if SetVariable is not supported If SetVariable at runtime is not supported by the firmware we never assign a callback for that function. At the same time mount the efivarfs as RO so no one can call that. However, we never check the permission flags when someone remounts the filesystem as RW. As a result this leads to a crash (CVE-2023-52463)
In the Linux kernel, the following vulnerability has been resolved:
mfd: syscon: Fix null pointer dereference in of_syscon_register()
kasprintf() returns a pointer to dynamically allocated memorywhich can be NULL upon failure.
(CVE-2023-52467)
In the Linux kernel, the following vulnerability has been resolved:
calipso: fix memory leak in netlbl_calipso_add_pass() (CVE-2023-52698)
An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access. (CVE-2023-6040)
A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return. (CVE-2023-6915)
An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service. (CVE-2024-0565)
An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2024-0646)
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the current generation instead of the next generation before freeing it, but only flags it inactive in the next generation, making it possible to free the element multiple times, leading to a double free vulnerability.
We recommend upgrading past commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7. (CVE-2024-1085)
In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_tcam: Fix stack corruption When tc filters are first added to a net device, the corresponding local port gets bound to an ACL group in the device. (CVE-2024-26586)
bpf: Fix re-attachment branch in bpf_tracing_prog_attach
The following case can cause a crash due to missing attach_btf:
1) load rawtp program2) load fentry program with rawtp as target_fd3) create tracing link for fentry program with target_fd = 04) repeat 3 (CVE-2024-26591)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
