Hi!
* CVE short summaryThese summaries are not so short; I simply skip them and go to full list. Perhaps they don't need to be included, or could include only CVEs where we need to take an action? * CVE detailThis one is queued for 5.10.62, so this is getting fixed for us. CVE-2021-3743: out-of-bound Read in qrtr_endpoint_post in net/qrtr/qrtr.cFixes are queued for 4.19 and 5.10.62, so this is getting fixed for us. CVE-2021-3753: A out-of-bounds caused by the race of KDSETMODE in vtAgreed, fixed in 4.19.192 and 4.4.270. Nothing for us to do there. Updated CVEsFixed in 4.14 but not 4.4. stable/4.14: [2cbb22fd4b4fb4d0822d185bf5bd6d027107bfda,Diffstat looks like this: key.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) main.c | 5 +++++ 1 file changed, 5 insertions(+) ath.h | 1 + key.c | 4 ++-- 2 files changed, 3 insertions(+), 2 deletions(-) ath.h | 2 +- ath5k/mac80211-ops.c | 2 +- ath9k/htc_drv_main.c | 2 +- ath9k/main.c | 5 ++--- key.c | 34 +++++++++++++++++----------------- 5 files changed, 22 insertions(+), 23 deletions(-) hw.h | 1 main.c | 87 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- 2 files changed, 87 insertions(+), 1 deletion(-) Best regards, Pavel -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany

Hi,
toggle quoted messageShow quoted text
-----Original Message-----I checked the patch application and build at hand. We can backport without any changes to 4.4 tree. But I don't have this device, so I can't confirm the working. Best regards, Nobuhiro

This weekly report mail contains full list which are new CVEs, updated CVEs, and currently tracking CVEs, so summary can be removed or make it simple I think. I'll write a new summary style that includes CVEs which we need to take care of.
