Summary
In the Linux kernel, the iwlwifi (mvm) driver's P2P-Device binding handling can leave the phy_ctxt pointer as a PHY cache after remain-on-channel ends. A subsequent binding update by the station interface re-adds the P2P-Device to the binding, and its removal deletes the PHY context still in the binding, causing a firmware crash.
Risk Assessment
This can lead to Wi-Fi firmware crashes and loss of network connectivity on affected devices.
Recommendation
Update the Linux kernel to a version with the fix that adds a boolean controlling whether the P2P-Device should be added to the binding.
Other vulnerabilities in Linux kernel
See all- CVE-2026-98162Unknown
In the Linux kernel, the smb2_tree_connect() function of the SMB server (ksmbd) leaks a tree connection. When ksmbd_iov_pin_rsp() fails, the newly created tree connection is not disconnected, leading to a resource leak.
- CVE-2026-98160Unknown
In the Linux kernel, the staging rtl8723bs driver's rtw_sdio_if1_init() function frees padapter->HalData with kfree(), even though it was allocated via vzalloc(). Using kfree() to release a vmalloc-backed buffer can lead to memory corruption.
- CVE-2026-100079Unknown
In the Linux kernel, the USB Type-C (ucsi) subsystem's ucsi_register() creates per-instance debugfs entries, but ucsi_unregister() keeps them until ucsi_destroy(). Drivers like ucsi_glink that unregister/register the same UCSI instance across remoteproc restart then try to create an already existing debugfs directory.
- CVE-2026-100078Unknown
In the Linux kernel, the iwlwifi (mei) driver's iwl_mei_write_cyclic_buf() function receives an incorrect first argument — the q_head pointer is passed instead of cldev. The bug has been fixed.
- CVE-2026-100077Unknown
In the Linux kernel, the drm/msm driver does not safely retire a hung submit before GPU recovery completes. Retiring the submit triggers BO free, which can result in GPU pagefaults since the GPU may be actively accessing those BOs.
- CVE-2026-100074Unknown
In the Linux kernel, a bug was fixed where the BPF_REFCOUNT field was not marked as unique, although it should be. The fix addresses this oversight.
- CVE-2026-100073Unknown
In the Linux kernel, a bug in the ext4 filesystem related to transaction overflow during writeback was fixed. A previous fix was too eager in reducing reserved transaction credits, leading to insufficient reservation in some corner cases. The fix uses ext4_meta_trans_blocks() for a correct upper bound estimate.
- CVE-2026-100072Unknown
In the Linux kernel, a problem in the ACPI subsystem was fixed where the use of acpi_get_first_physical_node() in acpi_platform_fill_resource() and acpi_create_platform_device() was unsafe because the returned device could be freed at any time. The fix replaces it with acpi_bus_get_primary_device() and adjusts the code to call it only once.
- CVE-2026-100071Unknown
In the Linux kernel, a memory leak in the HSR (High-availability Seamless Redundancy) module was fixed. When hsr_dev_finalize() fails after registering an RX handler, dynamic nodes learned in that window are not released. The fix frees both dynamic databases in the error unwind path.
- CVE-2026-100070Unknown
In the Linux kernel, a bug in the netfilter nf_nat_sip module was fixed where the offset was not rewound when NAT shrinks the packet. If map_addr() changes the packet length, coff may point to an incorrect position, potentially causing subsequent Contact headers to be skipped and leaking internal network details.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix P2P-Device binding handling Our binding handling for P2P-Device can run into the following scenario, as observed by our testing: - a station interface is connected on some channel - the P2P-Device does a remain-on-channel (ROC) on that channel - the ROC ends, and the P2P-Device is removed from the binding, but the phy_ctxt pointer is left around as a PHY cache so we don't need to recalibrate to the channel again and again in case it's not shared - a binding update by the station interface, even a removal, will re-add the P2P-Device to the binding - the P2P-Device is removed, which removes the PHY context, but it's still in the binding so the firmware crashes Since the P2P device is removed from the binding and only re- added by unrelated code, but we want to keep the phy_ctxt around as a cache for future ROC usage, fix it by adding a boolean that indicates whether or not the P2P-Device should be added to the binding, and handle that in the binding iterator. That way, the station interface cannot re-add the P2P-Device to the binding when that isn't active.
