But the advertisement handler doesn't free it. So, memory leak would occur. The Linux kernel CVE team has assigned CVE-2022-49461 to this issue. Affected and fixed versions =========================== Issue introduced in 5.16 with commit cbc21dc1cfe949e37b2a54c71511579f1899e8d4 and fixed in 5.17.14 with commit 19bb2d57eac86a368839a92117d8a10ab7183623 Issue introduced in 5.16 with commit cbc21dc1cfe949e37b2a54c71511579f1899e8d4 and fixed in 5.18.3 with commit e7322da399fb86a2072f008b56f7160afa1b2051 Issue introduced in 5.16 with commit cbc21dc1cfe949e37b2a54c71511579f1899e8d4 and fixed in 5.19 with commit fe29794c3585d039fefebaa2b5a4932a627ad4fd Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2022-49461 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/amt.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/19bb2d57eac86a368839a92117d8a10ab7183623 https://git.kernel.org/stable/c/e7322da399fb86a2072f008b56f7160afa1b2051 https://git.kernel.org/stable/c/fe29794c3585d039fefebaa2b5a4932a627ad4fd
