CVE-2023-53705 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix out-of-bounds access in ipv6_find_tlv() optlen is fetched without checking whether there is more than one byte to parse. It can lead to out-of-bounds access. Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
A vulnerability allowing out-of-bounds access has been identified in the Linux kernel's IPv6 extension header processing. The issue arises in the 'ipv6_find_tlv' function, where the length of the option is retrieved without verifying if there is more than one byte available to read. This oversight can lead to memory access violations. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been addressed.
