CVE-2023-54135

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> maple_tree: fix potential out-of-bounds access in mas_wr_end_piv()<br /> <br /> Check the write offset end bounds before using it as the offset into the<br /> pivot array. This avoids a possible out-of-bounds access on the pivot<br /> array if the write extends to the last slot in the node, in which case the<br /> node maximum should be used as the end pivot.<br /> <br /> akpm: this doesn&amp;#39;t affect any current callers, but new users of mapletree<br /> may encounter this problem if backported into earlier kernels, so let&amp;#39;s<br /> fix it in -stable kernels in case of this.
