https://notcve.org/view.php?id=CVE-2022-48790
In the Linux kernel, the following vulnerability has been resolved: nvme: fix a possible use-after-free in controller reset during load Unlike .queue_rq, in .submit_async_event drivers may not check the ctrl readiness for AER submission. This may lead to a use-after-free condition that was observed with nvme-tcp. The race condition may happen in the following scenario: 1. driver executes its reset_ctrl_work 2. -> nvme_stop_ctrl - flushes ctrl async_event_work 3. ctrl sends AEN which is received by the host, which in turn schedules AEN handling 4. teardown admin queue (which releases the queue socket) 5. AEN processed, submits another AER, calling the driver to submit 6. driver attempts to send the cmd ==> use-after-free In order to fix that, add ctrl state check to validate the ctrl is actually able to accept the AER submission. This addresses the above race in controller resets because the driver during teardown should: 1. change ctrl state to RESETTING 2. flush async_event_work (as well as other async work elements) So after 1,2, any other AER command will find the ctrl state to be RESETTING and bail out without submitting the AER. • https://git.kernel.org/stable/c/a25e460fbb0340488d119fb2e28fe3f829b7417e https://git.kernel.org/stable/c/70356b756a58704e5c8818cb09da5854af87e765 https://git.kernel.org/stable/c/0ead57ceb21bbf15963b4874c2ac67143455382f https://git.kernel.org/stable/c/e043fb5a0336ee74614e26f0d9f36f1f5bb6d606 https://git.kernel.org/stable/c/9e956a2596ae276124ef0d96829c013dd0faf861 https://git.kernel.org/stable/c/0fa0f99fc84e41057cbdd2efbfe91c6b2f47dd9d •

https://notcve.org/view.php?id=CVE-2022-48787
In the Linux kernel, the following vulnerability has been resolved: iwlwifi: fix use-after-free If no firmware was present at all (or, presumably, all of the firmware files failed to parse), we end up unbinding by calling device_release_driver(), which calls remove(), which then in iwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However the new code I added will still erroneously access it after it was freed. Set 'failure=false' in this case to avoid the access, all data was already freed anyway. • https://git.kernel.org/stable/c/8e10749fa1a454c1e7214f36cec83241f5a36ef1 https://git.kernel.org/stable/c/1d7cc54137a4f28506dc7beac235b240b08f4e59 https://git.kernel.org/stable/c/0446cafa843e6db4982731c167e11c80d42be7e2 https://git.kernel.org/stable/c/febab6b60d61d13cd9f30a2991deea56df39567d https://git.kernel.org/stable/c/e23f075d77987de4215c8e0696f28bcc707506f7 https://git.kernel.org/stable/c/6b5ad4bd0d78fef6bbe0ecdf96e09237c9c52cc1 https://git.kernel.org/stable/c/d3b98fe36f8a06ce654049540773256ab59cb53d https://git.kernel.org/stable/c/7d6475179b85a83186ccce59cdc359d4f •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48786 – vsock: remove vsock from connected table when connect is interrupted by a signal
https://notcve.org/view.php?id=CVE-2022-48786
In the Linux kernel, the following vulnerability has been resolved: vsock: remove vsock from connected table when connect is interrupted by a signal vsock_connect() expects that the socket could already be in the TCP_ESTABLISHED state when the connecting task wakes up with a signal pending. If this happens the socket will be in the connected table, and it is not removed when the socket state is reset. In this situation it's common for the process to retry connect(), and if the connection is successful the socket will be added to the connected table a second time, corrupting the list. Prevent this by calling vsock_remove_connected() if a signal is received while waiting for a connection. This is harmless if the socket is not in the connected table, and if it is in the table then removing it will prevent list corruption from a double add. Note for backporting: this patch requires d5afa82c977e ("vsock: correct removal of socket from the list"), which is in all current stable trees except 4.9.y. • https://git.kernel.org/stable/c/d021c344051af91f42c5ba9fdedc176740cbd238 https://git.kernel.org/stable/c/0bb88f3f7e8d506f3efe46d694964117e20efbfc https://git.kernel.org/stable/c/e3b3939fd137aab6d00d54bee0ee9244b286a608 https://git.kernel.org/stable/c/2910bcb9f67551a45397735e47b6d456eb8cd549 https://git.kernel.org/stable/c/5f326fe2aef411a6575628f92bd861463ea91df7 https://git.kernel.org/stable/c/87cd1bbd6677411e17369cd4b7389ab1e1fdba44 https://git.kernel.org/stable/c/787468ee7a435777521d33399d012fd591ae2f94 https://git.kernel.org/stable/c/addd62a8cb6fa90aa322365c62487da61 •
