Linux Distros Unpatched Vulnerability : CVE-2026-45962

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ublk: Validate SQE128 flag before accessing the cmd ublkctrlcmddump accesses header sqe-cmd before IOURINGFSQE128 flag check. This could cause out of boundary...

CVE-2026-45958

A flaw was found in the Linux kernel's drm/exynos: vidi driver. A local user could exploit this vulnerability by directly dereferencing a user pointer in the vidiconnectionioctl function. This allows for arbitrary kernel memory access from user space, potentially leading to privilege escalation o...

CVE-2026-45967

A flaw was found in the Linux kernel. Specifically, a bug in the mapdirectvalueaddr function, which is part of the Berkeley Packet Filter BPF instruction array map, leads to incorrect address calculations when dealing with non-zero offsets. This issue could result in the kernel accessing unintend...

CVE-2026-45974

A flaw was found in the Linux kernel's btrfs filesystem. The btrfsquotaenable function contains a logic error where it attempts to access an invalid memory location if a specific key is not found during a search operation. This incorrect handling of search results can lead to invalid leaf access,...

CVE-2026-46007

A flaw was found in the Linux kernel's hwmon powerz component. This vulnerability is caused by cacheline sharing between the transfer buffer and a mutex during Direct Memory Access DMA operations. This architectural issue can lead to unexpected behavior or data corruption, impacting system...

CVE-2026-46081

A flaw was found in the Linux kernel's asynchronous compression acomp subsystem. When an asynchronous hardware implementation, such as the QAT driver, completes a request that uses the DMA virtual address interface, an incorrect pointer is stored. This leads to memory corruption within the...

CVE-2026-46033

A flaw was found in the Linux kernel's authencesn cryptographic module. This vulnerability arises from insufficient validation of cryptographic digest sizes during the creation of new instances. A local attacker could exploit this by providing a malformed input, leading to an out-of-bounds memory...

CVE-2026-46037

A flaw was found in the Linux kernel, specifically within its IPv4 Internet Control Message Protocol ICMP component. This vulnerability occurs because the system does not properly check the type of ICMP replies before attempting to process them. An attacker could potentially exploit this by sendi...

CVE-2026-46091

A flaw was found in the igorplugusb component of the Linux kernel. The USB request structure, when handled by Direct Memory Access DMA on certain host controllers, did not properly follow DMA coherency rules. This oversight could lead to data integrity issues or unexpected system behavior, as the...
