CVE-2023-6121

CVE-2023-6121 is an out-of-bounds read in the Linux kernel’s NVMe-oF/TCP subsystem. The issue can be triggered by a crafted remote TCP packet, causing a heap-based overflow that may cause kmalloc data to be printed and potentially leaked to the kernel ring buffer (dmesg). Affected: Linux kernel N...

In the Linux kernel, the following vulnerability has been resolved: nvme-core: fix devpmqos memleak Call devpmqoshidelatencytolerance in the error unwind patch to avoid following kmemleak:- blktests master kmemleak-clear; ./check nvme/044; blktests master kmemleak-scan ; kmemleak-show nvme/044 Te...

kernel: nvme-tcp: don't access released socket during error recovery

A race condition leading to NULL pointer dereference was found in the Linux kernel NVMe-over-TCP driver's error recovery handling. A local user with privileges to execute NVMe management commands can run the 'nvme list' command while NVMe-over-TCP error recovery work is temporarily failing...

kernel: nvme-core: fix memory leak in dhchap_secret_store

A memory leak vulnerability was found in the NVMe core driver in the Linux kernel. In nvmectrldhchapsecretstore, the dhchapsecret buffer is not freed before returning in certain code paths, causing memory to be leaked each time the secret is stored. This can lead to memory exhaustion over time wi...

kernel: nvme-pci: fix mempool alloc size

A flaw was addressed in the Linux kernel’s nvme-pci driver related to how the driver calculated the worst-case number of PRP Physical Region Page lists required for a given I/O request. The implementation previously rounded the allocation to one list instead of correctly converting the maximum si...
