CVE-2026-53007
5.5 · MEDIUMOverview
CVE-2026-53007 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 24, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
ice: fix potential NULL pointer deref in error path of ice_set_ringparam()
ice_set_ringparam nullifies tstamp_ring of temporary tx_rings, without
clearing ICE_TX_RING_FLAGS_TXTIME bit.
When ICE_TX_RING_FLAGS_TXTIME is set and the subsequent
ice_setup_tx_ring() call fails, a NULL pointer dereference could happen
in the unwinding sequence:
ice_clean_tx_ring()
-> ice_is_txtime_cfg() == true (ICE_TX_RING_FLAGS_TXTIME is set)
-> ice_free_tx_tstamp_ring()
-> ice_free_tstamp_ring()
-> tstamp_ring->desc (NULL deref)
Clear ICE_TX_RING_FLAGS_TXTIME bit to avoid the potential issue.
Note that this potential issue is found by manual code review.
Compile test only since unfortunately I don't have E830 devices.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
