The vulnerability of the otx2_tc_add_flow() function in the drivers/net/ethernet/marvell/octeontx2/nic/otx2_tc.c file of the Ethernet network adapter driver for the Marvell-based Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the otx2tcaddflow function in the drivers/net/ethernet/marvell/octeontx2/nic/otx2tc.c file of the Ethernet network adapter driver for the Linux operating system is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker t...

Linux Distros Unpatched Vulnerability : CVE-2025-39978

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - octeontx2-pf: Fix potential use after free in otx2tcaddflow This code calls kfreercunewnode, rcu and then dereferences newnode and then dereferences it on the...

CVE-2025-39978

The CVE-2025-39978 issue involves the octeontx2-pf driver (Linux kernel) in otx2_tc_add_flow(): after calling kfree_rcu(new_node, rcu), the code dereferences new_node on subsequent lines and then acquires a mutex, which is not within a safe RCU region. This is a use-after-free/root cause: freed m...
