CVE-2021-28691 HIGH 7.8 linux linux_kernel Guest triggered use-after-free in Linux xen-netback A malicious or buggy network PV frontend can force Linux netback to disable the interface and terminate the receive kernel thread associated with queue 0 in response to the frontend sending a malformed packet 0.4%
CVE-2021-3483 HIGH 7.8 debian debian_linux A flaw was found in the Nosy driver in the Linux kernel.

CVE-2008-3247 HIGH 7.2 linux linux_kernel The LDT implementation in the Linux kernel 2.6.25.x before 2.6.25.11 on x86_64 platforms uses an incorrect size for ldt_desc, which allows local users to cause a denial of service (system crash) or possibly gain privileges via unspecified vectors. 0.4%
CVE-2005-0178 MED 6.2 linux linux_kernel Race condition in the setsid function in Linux before 2.6.8.1 allows local users to cause a denial of service (crash) and possibly access portions of kernel memory, related to TTY changes, locking, and semaphores. 0.4%
CVE-2024-44988 HIGH 8.8 linux linux_kernel In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: Fix out-of-bound access If an ATU violation was caused by a CPU Load operation, the SPID could be larger than DSA_MAX_PORTS (the size of mv88e6xxx_chip.ports[] array). 0.4%
CVE-2023-31082 MED 5.5 linux linux_kernel An issue was discovered in drivers/tty/n_gsm.c in the Linux kernel 6.2. There is a sleeping function called from an invalid context in gsmld_write, which will block the kernel. Note: This has been disputed by 3rd parties as not a valid vulnerability. 0.4%
CVE-2020-29368 HIGH 7.0 linux linux_kernel An issue was discovered in __split_huge_pmd in mm/huge_memory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1. 0.4%
CVE-2018-16882 HIGH 8.8 canonical ubuntu_linux A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_ 0.4%
CVE-2014-3917 LOW 3.3 linux linux_kernel kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value o 0.4%
