CVE-2021-4090 |
An out-of-bounds (OOB) memory write flaw was found in the NFSD in the Linux kernel. Missing sanity may lead to a write beyond bmval[bmlen-1] in nfsd4_decode_bitmap4 in fs/nfsd/nfs4xdr.c. In this flaw, a local attacker with user privilege may gain access to out-of-bounds memory, leading to a system integrity and confidentiality threat. Published: February 18, 2022; 1:15:10 PM -0500 |
V4.0:(not available) V3.1: 7.1 HIGH V2.0: 6.6 MEDIUM |
CVE-2021-20322 |
A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. Published: February 18, 2022; 1:15:09 PM -0500 |
V4.0:(not available) V3.1: 7.4 HIGH V2.0: 5.8 MEDIUM |
CVE-2021-20321 |
A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 4.7 MEDIUM V2.0: 4.7 MEDIUM |
CVE-2021-20320 |
A flaw was found in s390 eBPF JIT in bpf_jit_insn in arch/s390/net/bpf_jit_comp.c in the Linux kernel. In this flaw, a local attacker with special user privilege can circumvent the verifier and may lead to a confidentiality problem. Published: February 18, 2022; 1:15:08 PM -0500 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
