[PATCH OLK-6.6 v2] media: dvb-frontends: dib3000mb: fix uninit-value in dib3000_write_reg
by Ye Bin 10 Jan '25

10 Jan '25

From: Nikita Zhandarovich <n.zhandarovich(a)fintech.ru> mainline inclusion from mainline-v6.13-rc4 commit 2dd59fe0e19e1ab955259978082b62e5751924c7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBG2PJ CVE: CVE-2024-56769 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Syzbot reports [1] an uninitialized value issue found by KMSAN in dib3000_read_reg(). Local u8 rb[2] is used in i2c_transfer() as a read buffer; in case that call fails, the buffer may end up with some undefined values. Since no elaborate error handling is expected in dib3000_write_reg(), simply zero out rb buffer to mitigate the problem.
