Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Improper locking

EUVDB-ID: #VU92027

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-2024-27397

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the __nft_rbtree_insert(), nft_rbtree_deactivate() and nft_rbtree_gc() functions in net/netfilter/nft_set_rbtree.c, within the pipapo_get(), nft_pipapo_get(), nft_pipapo_insert(), pipapo_gc() and pipapo_deactivate() functions in net/netfilter/nft_set_pipapo.c, within the nft_rhash_key(), nft_rhash_cmp(), nft_rhash_lookup(), nft_rhash_get(), nft_rhash_update(), nft_rhash_insert() and nft_rhash_deactivate() functions in net/netfilter/nft_set_hash.c, within the nft_trans_gc_catchall_sync() and nf_tables_valid_genid() functions in net/netfilter/nf_tables_api.c. A local user can perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.
