kernel: out-of-bounds read in pci_dev_for_each_resource()

An out-of-bounds read flaw was found in pcidevforeachresource in the Linux Kernel. The pointer in the pcidevforeachresource may be wrong. For example, it might be used for the out-of-bounds read. This issue was identified by the Coverity static analysis tool, which flagged a pointer res that coul...

kernel: tick/nohz: unexport __init-annotated tick_nohz_full_setup()

In the Linux kernel, the following vulnerability has been resolved: tick/nohz: unexport init-annotated ticknohzfullsetup EXPORTSYMBOL and init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated init. The access to ...

kernel: netfilter: nf_tables: set dormant flag on hook register failure

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: set dormant flag on hook register failure We need to set the dormant flag again if we fail to register the hooks. During memory pressure hook registration can fail and we end up with a table marked as active...

A flaw was found in the bnxten module in the Linux kernel. A double DMA unmapping can trigger a kernel warning and cause a denial of service...

kernel: iommu: Don't reserve 0-length IOVA region

A flaw was found in the Linux kernel. When the bootloader/firmware does not set up the framebuffers, the address and size are 0 in the "iommu-addresses" property. If the IOVA region is reserved with a 0 length, it corrupts the IOVA rbtree with an entry that has pfnhi pfnlo. If the intent is to us...

kernel: RDMA/mlx5: Fix fortify source warning while accessing Eth segment

A flaw was found in the Linux kernel's mlx5 InfiniBand driver. Certain scenarios could lead to a use-after-free issue, potentially allowing an attacker to escalate their privileges or affect system integrity or stability...
