Title
parport: Proper fix for array out-of-bounds access
Summary
In the Linux kernel, the following vulnerability has been resolved:
parport: Proper fix for array out-of-bounds access
The recent fix for array out-of-bounds accesses replaced sprintf()
calls blindly with snprintf(). However, since snprintf() returns the
would-be-printed size, not the actually output size, the length
calculation can still go over the given limit.
Use scnprintf() instead of snprintf(), which returns the actually
output letters, for addressing the potential out-of-bounds access
properly.

There is no race, no memory-layout guessing, and no per-attempt effort.\nPR:L - The sysctl entries are registered with .mode = 0444 and sysctl_perm() enforces nothing beyond that, so any unprivileged local account can read them. No capability, no root, and no user-namespace trickery is required.\nUI:N - The attacker performs the read themselves; no victim action, mount, or file-open by another user is needed.\nS:U - The corruption and the disclosure are confined to the kernel\u0027s own stack within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - memcpy(result, buffer, len) with len \u003e sizeof(buffer) copies hundreds of bytes of adjacent kernel stack into the sysctl output buffer, which is then copied straight to userspace \u2014 a direct kernel stack memory disclosure exposing stack canaries, saved registers, and kernel pointers usable to defeat KASLR.\nI:H - In do_autoprobe(), sizeof(buffer) - len underflows to a huge size_t once len exceeds 256, giving an unbounded write of peripheral-controlled string data past the end of a 256-byte stack buffer \u2014 overwriting saved registers and the return address, which is exploitable for control-flow hijacking.\nA:H - Stack corruption in these handlers triggers __stack_chk_fail() and a non-syncing kernel panic, as demonstrated in the original bug report\u0027s backtrace; an unprivileged user can induce it at will."
