Linux Distros Unpatched Vulnerability : CVE-2026-52969

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: Reject wrapped offset in kvmresetdirtygfn kvmresetdirtygfn guards the gfn range with if !memslot || offset + flsmask = memslot-npages return; but offset is...

EUVD-2026-38836

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: fix GAIT table indexing due to double-scaling pointer arithmetic kvms390pciaifenable, kvms390pciaifdisable, and aenhostforward index the GAIT by manually multiplying the index with sizeofstruct zpcigaite. Since...

CVE-2026-52969 KVM: Reject wrapped offset in kvm_reset_dirty_gfn()

In the Linux kernel, the following vulnerability has been resolved: KVM: Reject wrapped offset in kvmresetdirtygfn kvmresetdirtygfn guards the gfn range with if !memslot || offset + flsmask = memslot-npages return; but offset is u64 and the addition is unchecked. The check can be silently bypasse...

CVE-2026-52969

CVE-2026-52969 affects the Linux kernel KVM component. The vulnerability stems from an unchecked u64 addition in kvm_reset_dirty_gfn(), where the guard if (!memslot || (offset + __fls(mask)) >= memslot->npages) can be bypassed due to offset being 64‑bit. This can allow an out-of-bounds load...

CVE-2026-52969 KVM: Reject wrapped offset in kvm_reset_dirty_gfn()

In the Linux kernel, the following vulnerability has been resolved: KVM: Reject wrapped offset in kvmresetdirtygfn kvmresetdirtygfn guards the gfn range with if !memslot || offset + flsmask = memslot-npages return; but offset is u64 and the addition is unchecked. The check can be silently bypasse...

CVE-2026-52968

CVE-2026-52968 affects the Linux kernel KVM on s390. The root cause is double-scaling the GAIT table index: code in kvm_s390_pci_aif_enable(), kvm_s390_pci_aif_disable(), and aen_host_forward() multiplies the GAIT index by sizeof(struct zpci_gaite) even though gait is already a pointer to struct ...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: bpf: It is necessary to preserve the id of the register in the synclinked regs function. The synclinked regs function copies the id of knownreg to reg when propagating the bounds of knownreg to reg, using the offset of knownreg...

Astra Linux – Vulnerability in glib2.0

A flaw was discovered in glib. Missing validation of the offset and count parameters in the gbufferedinputstreampeek function can lead to an integer overflow during length calculations. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy,...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: - svcrdma: The use of rcpageoff for the byte offset in memcpy was corrected. - svcrdmacopyInlinerange: The page index rccurpage was added to the page base instead of the byte offset rcpageoff. Use rcpageoff to ensure that copi...

ImageMagick JP2 Decoder DoS

The vulnerability of the JP2 image decoding decoder in the console-based image editing software ImageMagick is related to a offset error of one unit. Exploiting this vulnerability can allow an attacker to cause a service failure...

Important: graphite2

Issue Overview: Graphite before 1.3.15 has an integer underflow and resultant out-of-bounds write via Graphite actions, because slotat does not ensure that an offset is within the allowed slot-map range. CVE-2026-50593 Affected Packages: graphite2 Note: This advisory is applicable to Amazon Linux...

RUSTSEC-2026-0186 Unchecked pointer offset in crate `memmap2`

Affected versionf of memmap2 did not perform enough validation on the offset and len parameters of Mmap::uncheckedadviserange, MmapMut::uncheckedadviseranage and MmapMut::flushasyncrange. This can cause undefined behavior due to invalid values being passed to pointer::offset and pointer::add when...

Affected versionf of memmap2 did not perform enough validation on the offset and len parameters of Mmap::unchecked advise range, MmapMut::unchecked advise ranage and MmapMut::flush async range. This can cause undefined behavior due to invalid values being passed to pointer::offset and pointer::ad...

CVE-2026-49271

libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.1, the uncompressed HEIF decoder validates explicit icef compressed-unit offsets using unitoffset + unitsize. Because the addition can wrap, a crafted HEIF file can pass the range check and then construct a vector...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB SetMap request via mapWidths indexing

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...
