Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of kernel installed on the remote host is prior to 5.10.215-203.850. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2024-056 advisory.2024-07-03: CVE-2024-26643 was added to this advisory.
2024-07-03: CVE-2024-26642 was added to this advisory.
2024-07-03: CVE-2023-52458 was added to this advisory.
2024-07-03: CVE-2024-25739 was added to this advisory.
2024-07-03: CVE-2023-52620 was added to this advisory.
2024-06-06: CVE-2024-35809 was added to this advisory.
2024-06-06: CVE-2023-52482 was added to this advisory.
In the Linux kernel, the following vulnerability has been resolved:
block: add check that partition length needs to be aligned with block size
Before calling add partition or resize partition, there is no checkon whether the length is aligned with the logical block size.If the logical block size of the disk is larger than 512 bytes,then the partition size maybe not the multiple of the logical block size,and when the last sector is read, bio_truncate() will adjust the bio size,resulting in an IO error if the size of the read command is smaller thanthe logical block size.If integrity data is supported, this will alsoresult in a null pointer dereference when calling bio_integrity_free. (CVE-2023-52458)
In the Linux kernel, the following vulnerability has been resolved:
x86/srso: Add SRSO mitigation for Hygon processors (CVE-2023-52482)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: disallow timeout for anonymous sets (CVE-2023-52620)
create_empty_lvol in drivers/mtd/ubi/vtbl.c in the Linux kernel through 6.7.4 can attempt to allocate zero bytes, and crash, because of a missing check for ubi->leb_size. (CVE-2024-25739)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout (CVE-2024-26643)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
The commit mutex should not be released during the critical sectionbetween nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GCworker could collect expired objects and get the released commit lockwithin the same GC sequence.
nf_tables_module_autoload() temporarily releases the mutex to loadmodule dependencies, then it goes back to replay the transaction again.Move it at the end of the abort phase after nft_gc_seq_end() is called.
(CVE-2024-26925)
In the Linux kernel, the following vulnerability has been resolved:
PCI/PM: Drain runtime-idle callbacks before driver removal (CVE-2024-35809)
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.
