漏洞描述
中文描述:

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于在重新分配SVE状态缓冲区之前未设置新的向量长度，可能导致内存损坏。

英文描述:

In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Set new vector length before reallocating As part of fixing the allocation of the buffer for SVE state when changing SME vector length we introduced an immediate reallocation of the SVE state, this is also done when changing the SVE vector length for consistency. Unfortunately this reallocation is done prior to writing the new vector length to the task struct, meaning the allocation is done with the old vector length and can lead to memory corruption due to an undersized buffer being used. Move the update of the vector length before the allocation to ensure that the new vector length is taken into account. For some reason this isn't triggering any problems when running tests on the arm64 fixes branch (even after repeated tries) but is triggering issues very often after merge into mainline.
