While this allocation failure is\nhandled properly and request is rejected, it results in syzkaller\nreports. Additionally, such request may put undue burden on the\nsystem which will try to free a lot of memory for a bogus request.\n\nFix it by limiting allowed number of slots to 100. This can easily\nbe extended if we see devices that can track more than 100 contacts.\n\n## Affected\n\n- `linux_kernel < 4.19.322`\n- `linux_kernel >= 4.20, < 5.4.284`\n- `linux_kernel >= 5.5, < 5.10.226`\n- `linux_kernel >= 5.11, < 5.15.167`\n- `linux_kernel >= 5.16, < 6.1.110`\n- `linux_kernel >= 6.2, < 6.6.51`\n- `linux_kernel >= 6.7, < 6.10.10`\n- `linux_kernel = 6.11`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.10.10`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
