| CVE-2019-25160 | Cri | 0.52 | 9.1 | 0.01 | Feb 26, 2024 | In the Linux kernel, the following vulnerability has been resolved: netlabel: fix out-of-bounds memory accesses There are two array out-of-bounds memory accesses, one in cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both errors are embarassingly simple, and the… | ||
| CVE-2023-32233 | Hig | 0.52 | 7.8 | 0.13 | May 8, 2023 | In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are… | ||
| CVE-2022-42896 | Hig | 0.52 | 8.0 | 0.02 | Nov 23, 2022 | There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively) remotely via Bluetooth. A remote attacker could execute code… | ||
| CVE-2021-4157 | Hig | 0.52 | 8.0 | 0.02 | Mar 25, 2022 | An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate… | ||
| CVE-2019-9500 | Hig | 0.52 | 7.9 | 0.04 | Jan 16, 2020 | The Broadcom brcmfmac WiFi driver prior to commit 1b5e2423164b3670e8bc9174e4762d297990deff is vulnerable to a heap buffer overflow. If the Wake-up on Wireless LAN functionality is configured, a malicious event frame can be constructed to trigger an heap buffer overflow in the… | ||
| CVE-2018-16884 | Hig | 0.52 | 8.0 | 0.01 | Dec 18, 2018 | A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel… | ||
