In the Linux kernel, the following vulnerability has been resolved: iscsiibft: Fix UBSAN shift-out-of-bounds warning in ibftattrshownic When performing an iSCSI boot using IPv6, iscsistart still reads the /sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix length is 64, this...

kernel: netfilter: ipset: add missing range check in bitmap_ip_uadt

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: add missing range check in bitmapipuadt When tbIPSETATTRIPTO is not present but tbIPSETATTRCIDR exists, the values of ip and ipto are slightly swapped. Therefore, the range check for ip should be done later, but...

kernel: arm64: mm: fix VA-range sanity check

A logic flaw was found in the Linux kernel's arm64 memory management subsystem. The virtual address range sanity check in createmappingnoalloc and updatemappingprot uses an incorrect condition that only excludes the KASAN shadow region and module region, rather than properly validating addresses...

kernel: nfsd: fix nfs4_openowner leak when concurrent nfsd4_open occur

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix nfs4openowner leak when concurrent nfsd4open occur The action force umountumount -f will attempt to kill all rpctask even umount operation may ultimately fail if some files remain open. Consequently, if an action attemp...

kernel: block: fix integer overflow in BLKSECDISCARD

A flaw was found in the Linux kernel's block subsystem. A local attacker with sufficient privileges could exploit an integer overflow vulnerability in the BLKSECDISCARD ioctl. This could lead to a near infinite loop within the blkdevissuesecureerase function, resulting in a Denial of Service DoS...

kernel: mm: resolve faulty mmap_region() error path behaviour

In the Linux kernel, the following vulnerability has been resolved: mm: resolve faulty mmapregion error path behaviour The mmapregion function is somewhat terrifying, with spaghetti-like control flow and numerous means by which issues can arise and incomplete state, memory leaks and other...

kernel: net: stmmac: dwmac-tegra: Read iommu stream id from device tree

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: dwmac-tegra: Read iommu stream id from device tree Nvidia's Tegra MGBE controllers require the IOMMU "Stream ID" SID to be written to the MGBEWRAPAXIASID0CTRL register. The current driver is hard coded to use MGBE0's...

kernel: hwmon: (w83627ehf) Fix underflows seen when writing limit attributes

This CVE has been marked as Rejected by the assigning CNA...

kernel: bpf: Make sure internal and UAPI bpf_redirect flags don't overlap

In the Linux kernel, the following vulnerability has been resolved: bpf: Make sure internal and UAPI bpfredirect flags don't overlap The bpfredirectinfo is shared between the SKB and XDP redirect paths, and the two paths use the same numeric flag values in the ri-flags field specifically,...

kernel: bpf: devmap: provide rxq after redirect

In the Linux kernel, the following vulnerability has been resolved: bpf: devmap: provide rxq after redirect rxq contains a pointer to the device from where the redirect happened. Currently, the BPF program that was executed after a redirect via BPFMAPTYPEDEVMAP does not have it set. This is...

kernel: net: add more sanity checks to qdisc_pkt_len_init()

A flaw was found in the Linux kernel's network handling, specifically within the qdiscpktleninit function. A local user could exploit this by crafting a malicious Generic Segmentation Offload GSO packet. Insufficient sanity checks in the virtionethdrtoskb function allow for an underflow in the...

kernel: selinux: ignore unknown extended permissions

In the Linux kernel, the following vulnerability has been resolved: selinux: ignore unknown extended permissions When evaluating extended permissions, ignore unknown permissions instead of calling BUG. This commit ensures that future permissions can be added without interfering with older kernels...

kernel: vsock: prevent null-ptr-deref in vsock_*[has_data|has_space]

In the Linux kernel, the following vulnerability has been resolved: vsock: prevent null-ptr-deref in vsockhasdata|hasspace Recent reports have shown how we sometimes call vsockhasdata when a vsock socket has been de-assigned from a transport see attached links, but we shouldn't. Previous commits...

kernel: net: flow_dissector: use DEBUG_NET_WARN_ON_ONCE

In the Linux kernel, the following vulnerability has been resolved: net: flowdissector: use DEBUGNETWARNONONCE The following splat is easy to reproduce upstream as well as in -stable kernels. Florian Westphal provided the following commit: d1dab4f71d37 "net: add and use skbgethashsymmetricnet" bu...
