Subject: Coverity: vgxy61_tx_from_ep(): Memory - corruptions
Date: Thu, 10 Nov 2022 08:27:39 -0800 [thread overview]
Message-ID: <202211100827.8A08F58A@keescook> (raw)
Hello!
This is an experimental semi-automated report about issues detected by
Coverity from a scan of next-20221110 as part of the linux-next scan project:
https://scan.coverity.com/projects/linux-next-weekly-scan
You're getting this email because you were associated with the identified
lines of code (noted below) that were touched by commits:
Thu Oct 27 14:37:38 2022 +0300
153e4ad44d60 ("media: i2c: Add driver for ST VGXY61 camera sensor")
Coverity reported the following:
*** CID 1527258: Memory - corruptions (OVERRUN)
drivers/media/i2c/st-vgxy61.c:1528 in vgxy61_tx_from_ep()
1522 * valid for hardware stuff.
1523 */
1524 for (p = 0; p < VGXY61_NB_POLARITIES; p++) {
1525 if (phy2log[p] != ~0)
1526 continue;
1527 phy2log[p] = l;
vvv CID 1527258: Memory - corruptions (OVERRUN)
vvv Overrunning array "log2phy" of 5 4-byte elements at element index 5 (byte offset 23) using index "l" (which evaluates to 5).
1528 log2phy[l] = p;
1529 l++;
1530 }
1531 for (l = 0; l < l_nb + 1; l++)
1532 polarities[l] = ep.bus.mipi_csi2.lane_polarities[l];
1533
If this is a false positive, please let us know so we can mark it as
such, or teach the Coverity rules to be smarter. If not, please make
sure fixes get into linux-next. :) For patches fixing this, please
include these lines (but double-check the "Fixes" first):
Reported-by: coverity-bot <keescook+coverity-bot@chromium.org>
Addresses-Coverity-ID: 1527258 ("Memory - corruptions")
Fixes: 153e4ad44d60 ("media: i2c: Add driver for ST VGXY61 camera sensor")
Note that l starts at 1, 2, or 4, so line 1529 could push it to 5, which
is out of bounds, etc...
Thanks for your attention!
