Description

tomoyo: don't emit warning in tomoyo_write_control()

In the Linux kernel, the following vulnerability has been resolved:

tomoyo: don't emit warning in tomoyo_write_control()

syzbot is reporting too large allocation warning at tomoyo_write_control(),

for one can write a very very long line without new line character. To fix

this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE,

for practically a valid line should be always shorter than 32KB where the

"too small to fail" memory-allocation rule applies.

One might try to write a valid line that is longer than 32KB, but such

request will likely fail with -ENOMEM. Therefore, I feel that separately

returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant.

There is no need to distinguish over-32KB and over-KMALLOC_MAX_SIZE.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
