GHSA-XJ6G-C6GV-VMJP
Vulnerability from github – Published: 2024-07-29 18:30 – Updated: 2024-08-26 15:31In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix netfs_page_mkwrite() to check folio->mapping is valid
Fix netfs_page_mkwrite() to check that folio->mapping is valid once it has taken the folio lock (as filemap_page_mkwrite() does). Without this, generic/247 occasionally oopses with something like the following:
BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor read access in kernel mode

GHSA-XJX5-8V38-Q6GH
Vulnerability from github – Published: 2026-01-25 15:30 – Updated: 2026-03-18 18:31In the Linux kernel, the following vulnerability has been resolved:
nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovec
Commit efa56305908b ("nvmet-tcp: Fix a kernel panic when host sends an invalid H2C PDU length") added ttag bounds checking and data_offset validation in nvmet_tcp_handle_h2c_data_pdu(), but it did not validate whether the command's data structures (cmd->req.sg and cmd->iov) have been properly initialized before processing H2C_DATA PDUs.
The nvmet_tcp_build_pdu_iovec() function dereferences these pointers without NULL checks. This can be triggered by sending H2C_DATA PDU immediately after the ICREQ/ICRESP handshake, before sending a CONNECT command or NVMe write command.
Attack vectors that trigger NULL pointer dereferences: 1. H2C_DATA PDU sent before CONNECT → both pointers NULL 2. H2C_DATA PDU for READ command → cmd->req.sg allocated, cmd->iov NULL 3. H2C_DATA PDU for uninitialized command slot → both pointers NULL
The fix validates both cmd->req.sg and cmd->iov before calling nvmet_tcp_build_pdu_iovec(). Both checks are required because: - Uninitialized commands: both NULL - READ commands: cmd->req.sg allocated, cmd->iov NULL - WRITE commands: both allocated

H2C_DATA PDU sent before CONNECT \u2192 both pointers NULL\n2. H2C_DATA PDU for READ command \u2192 cmd-\u003ereq.sg allocated, cmd-\u003eiov NULL\n3. H2C_DATA PDU for uninitialized command slot \u2192 both pointers NULL\n\nThe fix validates both cmd-\u003ereq.sg and cmd-\u003eiov before calling\nnvmet_tcp_build_pdu_iovec(). Both checks are required because:\n- Uninitialized commands: both NULL\n- READ commands: cmd-\u003ereq.sg allocated, cmd-\u003eiov NULL\n- WRITE commands: both allocated",

GHSA-XM5J-HMVJ-WR75
Vulnerability from github – Published: 2024-09-27 15:30 – Updated: 2025-11-04 00:31In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: tc358767: Check if fully initialized before signalling HPD event via IRQ
Make sure the connector is fully initialized before signalling any HPD events via drm_kms_helper_hotplug_event(), otherwise this may lead to NULL pointer dereference.

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.
