Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU105746
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-52927
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the nft_ct_set_zone_eval() and nft_ct_tmpl_alloc_pcpu() functions in net/netfilter/nft_ct.c, within the EXPORT_SYMBOL_GPL() and nf_ct_find_expectation() functions in net/netfilter/nf_conntrack_expect.c, within the init_conntrack() function in net/netfilter/nf_conntrack_core.c. A local user can perform a denial of service (DoS) attack.
MitigationUpdate the affected package linux to the latest version.
