一、漏洞信息
漏洞编号:CVE-2024-38575
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.6.0
CVSS V2.0分值:
BaseScore:0.0 None
Vector:CVSS:2.0/
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:wifi: brcmfmac: pcie: handle randbuf allocation failureThe kzalloc() in brcmf_pcie_download_fw_nvram() will return nullif the physical memory has run out. As a result, if we useget_random_bytes() to generate random bytes in the randbuf, thenull pointer dereference bug will happen.In order to prevent allocation failure, this patch adds a separatefunction using buffer on kernel stack to generate random bytes inthe randbuf, which could prevent the kernel stack from overflow.

CVE-2024-38575

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: pcie: handle randbuf allocation failure

The kzalloc() in brcmf_pcie_download_fw_nvram() will return null
if the physical memory has run out. As a result, if we use
get_random_bytes() to generate random bytes in the randbuf, the
null pointer dereference bug will happen.

In order to prevent allocation failure, this patch adds a separate
function using buffer on kernel stack to generate random bytes in
the randbuf, which could prevent the kernel stack from overflow.

The Linux kernel CVE team has assigned CVE-2024-38575 to this issue.

CVE-2024-38575

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: pcie: handle randbuf allocation failure

The kzalloc() in brcmf_pcie_download_fw_nvram() will return null
if the physical memory has run out. As a result, if we use
get_random_bytes() to generate random bytes in the randbuf, the
null pointer dereference bug will happen.

In order to prevent allocation failure, this patch adds a separate
function using buffer on kernel stack to generate random bytes in
the randbuf, which could prevent the kernel stack from overflow.
