In the Linux kernel, the following vulnerability has been resolved: media: dvb-core: Fix double free in dvb_register_device() In function dvb_register_device() -> dvb_register_media_device() -> dvb_create_media_entity(), dvb->entity is allocated and initialized. If the…

In the Linux kernel, the following vulnerability has been resolved: xhci: Remove device endpoints from bandwidth list when freeing the device Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed. If xHC host is dying or…

Memory corruption due to double free when multiple threads race to set the timestamp store.

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix double free in idxd_setup_wqs() The clean up in idxd_setup_wqs() has had a couple bugs because the error handling is a bit subtle. It's simpler to just re-write it in a cleaner way. The…

Within tcpreplay's tcprewrite, a double free vulnerability has been identified in the dlt_linuxsll2_cleanup() function in plugins/dlt_linuxsll2/linuxsll2.c. This vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes the cleanup routine multiple times on the…

In the Linux kernel, the following vulnerability has been resolved: net: fec: Better handle pm_runtime_get() failing in .remove() In the (unlikely) event that pm_runtime_get() (disguised as pm_runtime_resume_and_get()) fails, the remove callback returned an error early. The…

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix double release compute pasid If kfd_process_device_init_vm returns failure after vm is converted to compute vm and vm->pasid set to compute pasid, KFD will not take pdd->drm_file reference. As…

In the Linux kernel, the following vulnerability has been resolved: igb: Fix igb_down hung on surprise removal In a setup where a Thunderbolt hub connects to Ethernet and a display through USB Type-C, users may experience a hung task timeout when they remove the cable between…

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix double free on tx path. We see kernel crashes and lockups and KASAN errors related to ax210 firmware crashes. One of the KASAN dumps pointed at the tx path, and it appears there is…

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix vm_bind_ioctl double free bug If the argument check during an array bind fails, the bind_ops are freed twice as seen below. Fix this by setting bind_ops to NULL after freeing. …

In the Linux kernel, the following vulnerability has been resolved: i2c: core: Fix double-free of fwnode in i2c_unregister_device() Before commit df6d7277e552 ("i2c: core: Do not dereference fwnode in struct device"), i2c_unregister_device() only called fwnode_handle_put() on…

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: fix double free in 'hci_discovery_filter_clear()' Function 'hci_discovery_filter_clear()' frees 'uuids' array and then sets it to NULL. There is a tiny chance of the following race: …

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix double destruction of rsv_qp rsv_qp may be double destroyed in error flow, first in free_mr_init(), and then in hns_roce_exit(). Fix it by moving the free_mr_init() call into hns_roce_v2_init(). …

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd9375: Fix double free of regulator supplies Driver gets regulator supplies in probe path with devm_regulator_bulk_get(), so should not call regulator_bulk_free() in error and remove paths to…

In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: pmf: Use device managed allocations If setting up smart PC fails for any reason then this can lead to a double free when unloading amd-pmf. This is because dev->buf was freed but never set…

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: avoid double free when failing to DMA-map FW msg The semantics are that caller of fbnic_mbx_map_msg() retains the ownership of the message on error. All existing callers dutifully free the page.

In the Linux kernel, the following vulnerability has been resolved: fs/nfs/read: fix double-unlock bug in nfs_return_empty_folio() Sometimes, when a file was read while it was being truncated by another NFS client, the kernel could deadlock because folio_unlock() was called…
