漏洞简述：
A vulnerability was found in Linux Kernel up to 6.12.4 (Operating System). It has been rated as critical.Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.Impacted is confidentiality, integrity, and availability.Upgrading to version 5.4.287, 5.10.231, 5.15.174, 6.1.120, 6.6.66 or 6.12.5 eliminates this vulnerability. Applying the patch 0f170e91d3063ca60baec4bd9f544faf3bfe29eb/70f3de869865f9c3da0508a5ea29f6f4c1889057/ad34306ac6836e5dd096b7d0ad4aa20cb7c8d9e5/98c03d05936d846073df8f550e9e8bf0dde1d77f/8e858930695d3ebec423e85384c95427258c294f/178e31df1fb3d9e0890eb471da16709cbc82edee/ab244dd7cf4c291f82faacdc50b45cc0f55b674d is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.

CVE-2024-56615

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

bpf: fix OOB devmap writes when deleting elements

Jordy reported issue against XSKMAP which also applies to DEVMAP - the
index used for accessing map entry, due to being a signed integer,
causes the OOB writes. Fix is simple as changing the type from int to
u32, however, when compared to XSKMAP case, one more thing needs to be
addressed.

When map is released from system via dev_map_free(), we iterate through
all of the entries and an iterator variable is also an int, which
implies OOB accesses. Again, change it to be u32.

Example splat below:
