Summary
In the Linux kernel, the following vulnerability has been resolved:
riscv:uprobe fix SR_SPIE set/clear handling
In riscv the process of uprobe going to clear spie before exec
the origin insn,and set spie after that.But When access the page
which origin insn has been placed a page fault may happen and
irq was disabled in arch_uprobe_pre_xol function,It cause a WARN
as follows.
There is no need to clear/set spie in arch_uprobe_pre/post/abort_xol.
We can just remove it.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: riscv:uprobe fix SR_SPIE set/clear management. En riscv, el proceso de uprobe borra spie antes de ejecutar la instrucci\u00f3n de origen y la configura despu\u00e9s. Sin embargo, al acceder a la p\u00e1gina donde se ha colocado la instrucci\u00f3n de origen, puede producirse un fallo de p\u00e1gina y la funci\u00f3n irq se ha deshabilitado en arch_uprobe_pre_xol.
