CVE-2021-47218
In the Linux kernel, the following vulnerability has been resolved: selinux: fix NULL-pointer dereference when hashtab allocation fails When the hash table slot array allocation fails in hashtabinit, h-size is left initialized with a non-zero value, but the h-htable pointer is NULL. This may then...
CVE-2021-47218
CVE-2021-47218: Linux kernel SELinux hashtab allocation failure could lead to NULL dereference. Root cause: on hashtab_init() allocation failure, h->size remains non-zero while h->htable is NULL, breaking hashtab_map() and hashtab_destroy() which assume non-empty hashtab. Mitigation in the ...

SUSE CVE-2021-38166
In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAPSYSADMIN capability...
Amazon Linux 2 : kernel (ALASKERNEL-5.10-2022-005)
The version of kernel installed on the remote host is prior to 5.10.62-55.141. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-005 advisory. A flaw was found in the Linux kernel's implementation of wireless drivers using the Atheros chipsets. An...
