An unprivileged local attacker on the host may use this flaw to cause a kernel oops condition and thus a denial of service by issuing a… | ||
| CVE-2021-4023 | Med | 0.36 | 5.5 | 0.00 | Mar 10, 2022 | A flaw was found in the io-workqueue implementation in the Linux kernel versions prior to 5.15-rc1. The kernel can panic when an improper cancellation operation triggers the submission of new io-uring operations during a shortage of free space. This flaw allows a local user with… | ||
| CVE-2021-3732 | Med | 0.36 | 5.5 | 0.00 | Mar 10, 2022 | A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be accessible. | ||
| CVE-2021-3428 | Med | 0.36 | 5.5 | 0.00 | Mar 4, 2022 | A flaw was found in the Linux kernel. A denial of service problem is identified if an extent tree is corrupted in a crafted ext4 filesystem in fs/ext4/extents.c in ext4_es_cache_extent. Fabricating an integer overflow, A local attacker with a special user privilege may cause a… | ||
| CVE-2021-3744 | Med | 0.36 | 5.5 | 0.01 | Mar 4, 2022 | A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. |
