CVE-2023-1095: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list -- the list head is all zeroes, this results in a NULL pointer dereference.

Affected products

• Linux Linux Kernel: before 6.0 (fixed in 6.0)
• Red Hat Enterprise Linux: version 8.0 only; version 9.0 only
