High [CVE-2026-80571] papr-phy-attest - validate cmd.length, plug mem leak
CVE-2026-80571Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: papr-phy-attest - validate cmd.length, plug mem leak In papr_phy_attest_create_handle(), the params->cmd.length is not validated before use, which can result in a buffer overlow. Check it and return -EINVAL if it is either 0 or exceeds sizeof(params->cmd). Also, params is freed on the success path but not error. Free it on errors after memory allocation. And free it on negative fd. This vulnerability arises from insufficient validation of a command length parameter, which can lead to a buffer overflow. Such an overflow could be exploited by a local attacker to potentially execute arbitrary code or cause a system crash (denial of service). Additionally, improper memory deallocation in error handling paths…
