CVE-2021-47130

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix freeing unallocated p2pmem In case p2p device was found but the p2p pool is empty, the nvme target is still trying to free the sgl from the p2p pool instead of the regular sgl pool and causing a crash BUG is called...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the nvmet module releasing unallocated p2pmem...

kernel: use after free in nvmet_tcp_free_crypto in NVMe

A use-after-free vulnerability was found in drivers/nvme/target/tcp.c in nvmettcpfreecrypto due to a logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead t...

SUSE CVE-2021-47075

In the Linux kernel, the following vulnerability has been resolved: nvmet: fix memory leak in nvmetallocctrl When creating ctrl in nvmetallocctrl, if the cntlidmin is larger than cntlidmax of the subsystem, and jumps to the "outfreechangednslist" label, but the ctrl-sqs lack of be freed. Fix this...

SUSE CVE-2021-47041

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix incorrect locking in statechange sk callback We are not changing anything in the TCP connection state so we should not take a writelock but rather a read lock. This caused a deadlock when running nvmet-tcp and...

CVE-2021-47075

The CVE-2021-47075 entry concerns the Linux kernel nvmet subsystem. A memory leak in nvmet_alloc_ctrl() could occur when cntlid_min is larger than the subsystem’s cntlid_max, because the code may jump to out_free_changed_ns_list without freeing ctrl->sqs. The patch fixes this by jumping to the...

SUSE CVE-2021-46983

In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: Fix NULL deref when SEND is completed with error When running some traffic and taking down the link on peer, a retry counter exceeded error is received. This leads to nvmetrdmaerrorcomp which tried accessing the...

CVE-2021-47041

A flaw was found in the Linux Kernel, potentially allowing for a deadlock when running nvmet-tcp and nvme-tcp on the same system. This may lead to compromised Availability...

CVE-2021-46983

A flaw was found in an error-handling function in the Linux kernel's NVMe driver. This flaw allows an attacker with control over NVMe links to cause a denial of service. Mitigation Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a...
