Ubuntu Security Notice 5728-3 - Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the memory address space accounting implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5748-1 - It was discovered that Sysstat incorrectly handled certain arithmetic multiplications. An attacker could use this issue to cause Sysstat to crash, resulting in a denial of service, or possibly execute arbitrary code.

Researchers have disclosed details of three new security vulnerabilities affecting operational technology (OT) products from CODESYS and Festo that could lead to source code tampering and denial-of-service (DoS). The vulnerabilities, reported by Forescout Vedere Labs, are the latest in a long list of flaws collectively tracked under the name OT:ICEFALL. "These issues exemplify either an

A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the TDP MMU are enabled.

Tenda TX9 Pro v22.03.02.10 was discovered to contain a stack overflow via the list parameter at /goform/SetIpMacBind.

Improper Input Validation vulnerability in Mitsubishi Electric Corporation MELSEC iQ-R Series RJ71EN71 Firmware version "65" and prior and Mitsubishi Electric Corporation MELSEC iQ-R Series R04/08/16/32/120ENCPU Network Part Firmware version "65" and prior allows a remote unauthenticated attacker to cause a Denial of Service condition by sending specially crafted packets. A system reset is required for recovery.

VMware Tools for Windows (12.x.y prior to 12.1.5, 11.x.y and 10.x.y) contains a denial-of-service vulnerability in the VM3DMP driver. A malicious actor with local user privileges in the Windows guest OS, where VMware Tools is installed, can trigger a PANIC in the VM3DMP driver leading to a denial-of-service condition in the Windows guest OS.

An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.

Elon Musk-owned Starlink, WhiteHouse.gov, and the Prince of Wales were targeted by Killnet in apparent retaliation for its support of Ukraine.
