However, this creates a window where debugfs files are\nstill accessible after edt_ft5x06_ts_teardown_debugfs() frees\ntsdata->raw_buffer.\n\nTo prevent a use-after-free, protect the freeing of raw_buffer with the\ndevice mutex and set raw_buffer to NULL. The debugfs read function\nalready checks if raw_buffer is NULL under the same mutex, so this\nsafely avoids the use-after-free."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/input/touchscreen/edt-ft5x06.c"],"versions":[{"version":"68743c500c6eafcd0b16dc6067fea5bca0795eef","lessThan":"a516d43886623e3cca5fa3446bed8fc7c7982be2","status":"affected","versionType":"git"},{"version":"68743c500c6eafcd0b16dc6067fea5bca0795eef","lessThan":"9f6c5e7b747d40e1c65cbfcb975857d25154c075","status":"affected","versionType":"git"},{"version":"68743c500c6eafcd0b16dc6067fea5bca0795eef","lessThan":"f5f9e07060519e2287e99019a6de1eb3ebb65c37","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/input/touchscreen/edt-ft5x06.c"],"versions":[{"version":"6.17","status":"affected"},{"version":"0","lessThan":"6.17","status":"unaffected","versionType":"semver"},{"version":"6.18.27","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.4","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"6.18.27"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.0.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a516d43886623e3cca5fa3446bed8fc7c7982be2"},{"url":"https://git.kernel.org/stable/c/9f6c5e7b747d40e1c65cbfcb975857d25154c075"},{"url":"https://git.kernel.org/stable/c/f5f9e07060519e2287e99019a6de1eb3ebb65c37"}],"title":"Input: edt-ft5x06 - fix use-after-free in debugfs teardown","x_generator":{"engine":"bippy-1.2.0"}}}}
