| CVE-2023-52511 | Med | 0.35 | 5.3 | 0.01 | Mar 2, 2024 | In the Linux kernel, the following vulnerability has been resolved: spi: sun6i: reduce DMA RX transfer width to single byte Through empirical testing it has been determined that sometimes RX SPI transfers with DMA enabled return corrupted data. This is down to single or even… | ||

| CVE-2022-2588 | Med | 0.35 | 5.3 | 0.06 | Jan 8, 2024 | It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0. | ||
| CVE-2022-2585 | Med | 0.35 | 5.3 | 0.01 | Jan 8, 2024 | It was discovered that when exec'ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free. | ||

| CVE-2018-1000204 | Med | 0.35 | 5.3 | 0.02 | Jun 26, 2018 | Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in… | ||
| CVE-2015-5327 | Med | 0.35 | 6.5 | 0.02 | Sep 25, 2017 | Out-of-bounds memory read in the x509_decode_time function in x509_cert_parser.c in Linux kernels 4.3-rc1 and after. | ||
| CVE-2016-10318 | Med | 0.35 | 6.5 | 0.02 | Apr 4, 2017 | A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially… | ||
| CVE-2015-7513 | Med | 0.35 | 6.5 | 0.01 | Feb 8, 2016 | arch/x86/kvm/x86.c in the Linux kernel before 4.4 does not reset the PIT counter values during state restoration, which allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and… |
