Detailsinfo

A vulnerability was found in Linux Kernel up to 6.11.6. It has been classified as problematic. This affects the function xa_init_flags of the component rpcrdma. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: rpcrdma: Always release the rpcrdma_device's xa_array Dai pointed out that the xa_init_flags() in rpcrdma_add_one() needs to have a matching xa_destroy() in rpcrdma_remove_one() to release underlying memory that the xarray might have accrued during operation.

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2024-53077 since 11/19/2024. Technical details of the vulnerability are known, but there is no available exploit.
