CVE-2026-93266

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> arm64: RSI: fix field-spanning write warning in attestation token init<br /> <br /> The challenge is passed in registers a1 through a8. However, copying to<br /> &amp;regs.a1 makes FORTIFY treat the destination as the single a1 field,<br /> resulting in a field-spanning write warning. [1]<br /> <br /> Overlay the SMCCC register structure with an RSI-specific argument<br /> layout and copy the challenge into an explicit 64-byte array. This keeps<br /> the existing a1-a8 argument encoding while giving the copy a correctly<br /> sized destination object.<br /> <br /> [1]<br /> memcpy: detected field-spanning write (size 64) of single field "&amp;regs.a1" at ./arch/arm64/include/asm/rsi_cmds.h:119 (size 8)<br /> WARNING: ./arch/arm64/include/asm/rsi_cmds.h:119 at rsi_attestation_token_init+0xdc/0xf8 [arm_cca_guest], CPU#0: cat/3314
