Details
A vulnerability was found in Linux Kernel up to 6.1.92/6.6.32/6.8.11/6.9.2 and classified as critical. This issue affects the function devm_add_action_or_reset of the component hns3. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. The summary by CVE is:
In the Linux kernel, the following vulnerability has been resolved: drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset() pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action() fails, the irq vector is not freed, which leads to a memory leak. Replace the devm_add_action with devm_add_action_or_reset to ensure the irq vector can be destroyed when it fails.
The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2024-38603 since 06/18/2024. Technical details are known, but no exploit is available.
Upgrading to version 6.1.93, 6.6.33, 6.8.12 or 6.9.3 eliminates this vulnerability.
