CVSS: -EPSS: %CPEs: 9EXPL: 0CVE-2024-56700 – media: wl128x: Fix atomicity violation in fmc_send_cmd()
https://notcve.org/view.php?id=CVE-2024-56700
In the Linux kernel, the following vulnerability has been resolved: media: wl128x: Fix atomicity violation in fmc_send_cmd() Atomicity violation occurs when the fmc_send_cmd() function is executed simultaneously with the modification of the fmdev->resp_skb value. Consider a scenario where, after passing the validity check within the function, a non-null fmdev->resp_skb variable is assigned a null value. This results in an invalid fmdev->resp_skb variable passing the validity check. As seen in the later part of the function, skb = fmdev->resp_skb; when the invalid fmdev->resp_skb passes the check, a null pointer dereference error may occur at line 478, evt_hdr = (void *)skb->data; To address this issue, it is recommended to include the validity check of fmdev->resp_skb within the locked section of the function. This modification ensures that the value of fmdev->resp_skb does not change during the validation process, thereby maintaining its validity. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. • https://git.kernel.org/stable/c/e8454ff7b9a4d56f02c095bff12d3c92ef4c7fa6 https://git.kernel.org/stable/c/d16109c9fdc1b8cea4fe63b42e06e926c3f68990 https://git.kernel.org/stable/c/3c818ad07e964bca3d27adac1e1f50e1e3c9180e https://git.kernel.org/stable/c/d7408a052aa1b4f6fb6f1c7a8877b84017a07ac9 https://git.kernel.org/stable/c/ed228b74d8a500380150965d5becabf9a1e33141 https://git.kernel.org/stable/c/372dc9509122e5d45d4c12978e31c3c7d00aaca4 https://git.kernel.org/stable/c/378ce4e08ca2b1ac7bbf1d57b68643ca4226c5f8 https://git.kernel.org/stable/c/2e63c908de357048180516b84740ed62d •

https://notcve.org/view.php?id=CVE-2024-56698
In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: gadget: Fix looping of queued SG entries The dwc3_request->num_queued_sgs is decremented on completion. If a partially completed request is handled, then the dwc3_request->num_queued_sgs no longer reflects the total number of num_queued_sgs (it would be cleared). Correctly check the number of request SG entries remained to be prepare and queued. Failure to do this may cause null pointer dereference when accessing non-existent SG entry. • https://git.kernel.org/stable/c/c96e6725db9d6a04ac1bee881e3034b636d9f71c https://git.kernel.org/stable/c/8ceb21d76426bbe7072cc3e43281e70c0d664cc7 https://git.kernel.org/stable/c/0247da93bf62d33304b7bf97850ebf2a86e06d28 https://git.kernel.org/stable/c/c9e72352a10ae89a430449f7bfeb043e75c255d9 https://git.kernel.org/stable/c/1534f6f69393aac773465d80d31801b554352627 https://git.kernel.org/stable/c/b7c3d0b59213ebeedff63d128728ce0b3d7a51ec https://git.kernel.org/stable/c/70777a23a54e359cfdfafc625a57cd56434f3859 https://git.kernel.org/stable/c/b7fc65f5141c24785dc8c19249ca4efcf •

In the Linux kernel, the following vulnerability has been resolved: mfd: intel_soc_pmic_bxtwc: Use IRQ domain for USB Type-C device While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them. • https://git.kernel.org/stable/c/9c6235c8633210cc2da0882e2e9d6ff90aa37503 https://git.kernel.org/stable/c/0997e77c51330c2866a4f39480e762cca92ad953 https://git.kernel.org/stable/c/0b648968bfa4f5c9c4983bca9f2de17626ed6fb6 https://git.kernel.org/stable/c/23230ac3c5ca3f154b64849d1cf50583b4e6b98c https://git.kernel.org/stable/c/c310e6916c0b297011d0fec03f168a6b24e9e984 https://git.kernel.org/stable/c/e1ef62e8d262e3f27446d26742208c1c81e9ee18 https://git.kernel.org/stable/c/518e414d24e7037d6cc7198e942bf47fe6f5e8e1 https://git.kernel.org/stable/c/87a07a5b0b296e489c606ca95ffc16c18 •
