Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： wifi: iwlwifi: mvm: 修复 TXF 密钥清洗器中的差一（off-by-one）错误 函数使用循环变量 来记录最后一个匹配字节的位置。当找到完整密钥匹配时（即 ），变量 指向所匹配密钥的最后一个字节。因此， 的起始偏移量应为 ，而不是 。当前代码会将匹配区域前的一个字节置零，同时导致密钥的最后一个字节未被清洗（未被清零）。

Vulnerability Title
wifi: iwlwifi: mvm: fix off-by-one in TXF key sanitiser
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix off-by-one in TXF key sanitiser
iwl_mvm_frob_txf_key_iter() tracks the last matched byte position
in loop variable 'i'. When a full key match is found (match ==
keylen), 'i' points at the last byte of the matched key. The
memset start offset should therefore be i + 1 - keylen, not
i - keylen; the current code zeroes one byte before the match
and leaves the final key byte un-sanitised.
