CVE-2026-98188
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: p54: validate curve data length in the calibration curve converters
p54_convert_rev0() and p54_convert_rev1() read calibration curve data from the device-supplied EEPROM entry using channel and points-per-channel counts taken verbatim from that same entry, so an entry that declares more data than it carries drives an out-of-bounds read past the EEPROM buffer (verified with a KASAN reproducer of the conversion loop). The sibling converters p54_convert_output_limits() and p54_convert_db() already validate their counts against the entry length; this path was missed.
Reject the entry when the counts do not fit in the entry data.
