https://notcve.org/view.php?id=CVE-2024-43877
In the Linux kernel, the following vulnerability has been resolved: media: pci: ivtv: Add check for DMA map result In case DMA fails, 'dma->SG_length' is 0. This value is later used to access 'dma->SGarray[dma->SG_length - 1]', which will cause out of bounds access. Add check to return early on invalid value. Adjust warnings accordingly.

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-43876 – PCI: rcar: Demote WARN() to dev_warn_ratelimited() in rcar_pcie_wakeup()
https://notcve.org/view.php?id=CVE-2024-43876
In the Linux kernel, the following vulnerability has been resolved: PCI: rcar: Demote WARN() to dev_warn_ratelimited() in rcar_pcie_wakeup() Avoid large backtrace, it is sufficient to warn the user that there has been a link problem. Either the link has failed and the system is in need of maintenance, or the link continues to work and user has been informed. The message from the warning can be looked up in the sources. This makes an actual link issue less verbose. First of all, this controller has a limitation in that the controller driver has to assist the hardware with transition to L1 link state by writing L1IATN to PMCTRL register, the L1 and L0 link state switching is not fully automatic on this controller. In case of an ASMedia ASM1062 PCIe SATA controller which does not support ASPM, on entry to suspend or during platform pm_test, the SATA controller enters D3hot state and the link enters L1 state. If the SATA controller wakes up before rcar_pcie_wakeup() was called and returns to D0, the link returns to L0 before the controller driver even started its transition to L1 link state. At this point, the SATA controller did send an PM_ENTER_L1 DLLP to the PCIe controller and the PCIe controller received it, and the PCIe controller did set PMSR PMEL1RX bit. Once rcar_pcie_wakeup() is called, if the link is already back in L0 state and PMEL1RX bit is set, the controller driver has no way to determine if it should perform the link transition to L1 state, or treat the link as if it is in L0 state. Currently the driver attempts to perform the transition to L1 link state unconditionally, which in this specific case fails with a PMSR L1FAEG poll timeout, however the link still works as it is already back in L0 state. Reduce this warning verbosity. • https://git.kernel.org/stable/c/84b576146294c2be702cfcd174eaa74167e276f9 https://git.kernel.org/stable/c/2ae4769332dfdb97f4b6f5dc9ac8f46d02aaa3df https://git.kernel.org/stable/c/526a877c6273d4cd0d0aede84c1d620479764b1c https://git.kernel.org/stable/c/3ff3bdde950f1840df4030726cef156758a244d7 https://git.kernel.org/stable/c/c93637e6a4c4e1d0e85ef7efac78d066bbb24d96 •

https://notcve.org/view.php?id=CVE-2024-43873
In the Linux kernel, the following vulnerability has been resolved: vhost/vsock: always initialize seqpacket_allow There are two issues around seqpacket_allow: 1. seqpacket_allow is not initialized when socket is created. Thus if features are never set, it will be read uninitialized. 2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared, then seqpacket_allow will not be cleared appropriately (existing apps I know about don't usually do this but it's legal and there's no way to be sure no one relies on this). To fix: - initialize seqpacket_allow after allocation - set it unconditionally in set_features • https://git.kernel.org/stable/c/ced7b713711fdd8f99d8d04dc53451441d194c60 https://git.kernel.org/stable/c/ea558f10fb05a6503c6e655a1b7d81fdf8e5924c https://git.kernel.org/stable/c/3062cb100787a9ddf45de30004b962035cd497fb https://git.kernel.org/stable/c/30bd4593669443ac58515e23557dc8cef70d8582 https://git.kernel.org/stable/c/eab96e8716cbfc2834b54f71cc9501ad4eec963b https://git.kernel.org/stable/c/1e1fdcbdde3b7663e5d8faeb2245b9b151417d22 •
