CVE-2026-53336
UnknownSummary
In the Linux kernel, a vulnerability in the nvmem driver for ONIE-TLV layouts causes an infinite loop hang when encountering an unknown entry type (e.g., 0x41). The fix ensures offset incrementation for unknown types to break the loop.
Risk Assessment
The risk is a potential system hang (DoS) when reading EEPROM with vendor-specific entries, which may disrupt devices relying on this functionality.
Recommendation
Immediately update the Linux kernel to a version containing the fix (commit addressing the issue in nvmem/layouts/onie-tlv).
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: nvmem: layouts: onie-tlv: fix hang on unknown types The EEPROM on my board has a vendor specific entry of type 0x41. When stumbling upon that, this driver hangs in an endless loop. Fix it by keep incrementing the offset on unknown entries, so the loop will eventually stop.
