Vulnerability from github – Published: 2024-07-16 15:30 – Updated: 2024-07-17 21:31In the Linux kernel, the following vulnerability has been resolved:
ice: fix NULL pointer dereference in ice_update_vsi_tx_ring_stats()
It is possible to do NULL pointer dereference in routine that updates Tx ring stats. Currently only stats and bytes are updated when ring pointer is valid, but later on ring is accessed to propagate gathered Tx stats onto VSI stats.
Change the existing logic to move to next ring when ring is NULL.

Vulnerability from github – Published: 2024-10-21 18:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix null-ptr-deref when journal load failed.
During the mounting process, if journal_reset() fails because of too short journal, then lead to jbd2_journal_load() fails with NULL j_sb_buffer. Subsequently, ocfs2_journal_shutdown() calls jbd2_journal_flush()->jbd2_cleanup_journal_tail()-> __jbd2_update_log_tail()->jbd2_journal_update_sb_log_tail() ->lock_buffer(journal->j_sb_buffer), resulting in a null-pointer dereference error.
To resolve this issue, we should check the JBD2_LOADED flag to ensure the journal was properly loaded. Additionally, use journal instead of osb->journal directly to simplify the code.

Currently 'ar' reference is not added in skb_cb.

This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Sante PACS Server. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of HTTP Content-Length header. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-26770.

gve: add missing NULL check for gve_alloc_pending_packet() in TX DQO
gve_alloc_pending_packet() can return NULL, but gve_tx_add_skb_dqo() did not check for this case before dereferencing the returned pointer.
Add a missing NULL check to prevent a potential NULL pointer dereference when allocation fails.
This improves robustness in low-memory scenarios.

GHSA-7Q5J-M65F-W95R
Vulnerability from github – Published: 2025-07-04 15:31 – Updated: 2026-05-12 15:30In the Linux kernel, the following vulnerability has been resolved:
nfsd: Initialize ssc before laundromat_work to prevent NULL dereference
In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized, this can cause NULL pointer dereference.
Normally the delayed start of laundromat_work allows sufficient time for nfsd_ssc initialization to complete. However, when the kernel waits too long for userspace responses (e.g. in nfs4_state_start_net -> nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done -> cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the delayed work may start before nfsd_ssc initialization finishes.
Fix this by moving nfsd_ssc initialization before starting laundromat_work.

GHSA-7Q5M-QV9W-C8XX
Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-07-02 21:32In the Linux kernel, the following vulnerability has been resolved:
netfilter: revalidate bridge ports
ebt_redirect_tg() dereferences br_port_get_rcu() return without a NULL check, causing a kernel panic when the bridge port has been removed between the original hook invocation and an NFQUEUE reinject.
A mere NULL check isn't sufficient, however. As sashiko review points out userspace can not only remove the port from the bridge, it could also place the device in a different virtual device, e.g. macvlan.
If this happens, we must drop the packet, there is no way for us to reinject it into the bridge path.
Switch to _upper API, we don't need the bridge port structure. Also, this fix keeps another bug intact:
Both nfnetlink_log and nfnetlink_queue use CONFIG_BRIDGE_NETFILTER too aggressive, which prevents certain logging features when queueing in bridge family: NETFILTER_FAMILY_BRIDGE can be enabled while the old CONFIG_BRIDGE_NETFILTER cruft is off.
Fixes tag is a common ancestor, this was always broken.

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
