CVE-2026-53277
CVE-2026-53277 – Linux kernel (arm64 KVM) : A flaw where certain page-table walk operations (walk_s1 and kvm_walk_nested_s2) did not acquire the Sleepable RCU lock (SRCU) via kvm->srcu, risking memslot changes and potential instability during fault injection and Address Translation emulation. ...
Astra Linux – Vulnerability in Qemu
A reachable assertion issue was detected in the USB EHCI emulation code of QEMU. This issue can occur during the processing of USB requests due to a faulty handling of the DMA memory map. A malicious privileged user within the guest environment may exploit this flaw to send invalid USB requests,...
Astra Linux – Vulnerability in Linux, Linux 5.10
There is a bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by simulating an NFC device from user-space...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Mark the target gfn of the emulated atomic instruction as dirty. When emulating an atomic access on behalf of the guest, mark the target gfn as dirty if the CMPXCHG instruction attempts to execute but fails without...
Astra Linux – Vulnerability in Qemu
A use-after-free vulnerability was discovered in the LSI53C895A SCSI Host Bus Adapter emulation in QEMU. The flaw occurs during the processing of repeated messages to cancel the current SCSI request using the lsidomsgout function. This flaw allows a malicious privileged user within the guest to...
Astra Linux – Vulnerability in Qemu
QEMU 4.2.0 has a use-after-free issue in hw/net/e1000ecore.c, as a user of the guest OS can trigger an e1000e packet with the data’s address set to the e1000e’s MMIO address...
Astra Linux – Vulnerability in Qemu
A reentrancy issue related to DMA was discovered in the USB EHCI controller emulation of QEMU. EHCI does not verify whether the Buffer Pointer overlaps with its MMIO region when transferring USB packets. Crafted content may be written to the controller’s registers, potentially triggering...
Astra Linux – Vulnerability in Qemu
A out-of-bounds write flaw was discovered in the UAS USB-attached SCSI device emulation in QEMU in versions prior to 6.2.0-rc0. The device uses the guest-provided stream number without proper checking, which can lead to out-of-bounds access to the UASDevice-data3 and UASDevice-status3 fields. A...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Make ICCSGIEL1 undef in the absence of a vGICv3 On a system with a GICv3, if a guest has not been configured with a GICv3, and the host is not capable of emulating GICv2, writing to any of the ICCSGIEL1 registers will...
Astra Linux – Vulnerability in Qemu
A NULL pointer dereference flaw was discovered in the am53c974 SCSI host bus adapter emulation in QEMU in versions prior to 6.0.0. This issue occurs when handling the “Information Transfer” command. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a...
Astra Linux – Vulnerability in Qemu
A flaw was discovered in the QXL display device emulation in QEMU. The double retrieval of the guest-controlled values cursor-header.width and cursor-header.height can lead to the allocation of a small cursor object, followed by a subsequent heap-based buffer overflow. A malicious privileged gues...
Astra Linux – Vulnerability in Qemu
An infinite loop flaw was discovered in the USB xHCI controller emulation of QEMU while calculating the length of the Transfer Request Block TRB Ring. This flaw allows a privileged guest user to halt the QEMU process on the host, resulting in a denial of service...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Do not retire an aborted MMIO instruction Returning an abort to the guest for an unsupported MMIO access is a documented feature of the KVM UAPI. However, it’s clear that this functionality has been tested limitedly, ...
Astra Linux – Vulnerability in Qemu
An “off-by-one” error was detected in the SCSI device emulation in QEMU. This error could occur during the processing of MODE SELECT commands in modesensepage, if the ‘page’ argument is set to MODEPAGEALLS 0x3f. A malicious guest could exploit this flaw to potentially cause QEMU to crash, resulti...
