Kernel Live Patch Security Notice

Published Jul 16, 2024 · Updated Jun 3, 2026

Summary

It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code.(CVE-2023-6270)

It was discovered that the netfilter connection tracker for netlink in the
Linux kernel did not properly perform reference counting in some error
conditions. A local attacker could possibly use this to cause a denial of
service (memory exhaustion).(CVE-2023-7192)

In the Linux kernel, the following vulnerability has been
resolved: netfilter: nf_tables: disallow anonymous set with timeout flag
Anonymous sets are never used with timeout from userspace, reject this.
Exception to this rule is NFT_SET_EVAL to ensure legacy meters still work.(CVE-2024-26642)

In the Linux kernel, the following vulnerability has been
resolved: cifs: fix underflow in parse_server_interfaces() In this loop, we
step through the buffer and after each item we check if the size_left is
greater than the minimum size we need. However, the problem is that
'bytes_left' is type ssize_t while sizeof() is type size_t. That means that
because of type promotion, the comparison is done as an unsigned and if we
have negative bytes left the loop continues instead of ending.(CVE-2024-26828)

In the Linux kernel, the following vulnerability has been
resolved: netfilter: nft_set_pipapo: do not free live element (CVE-2024-26924)
