If we\nhave an incorrect pkt_len or pkt_tag, the input skb is considered invalid\nand dropped. All the associated packets already in skb_pool should be\ndropped and freed. Added a comment describing this issue.\n\nThe patch also makes remain_skb NULL after being processed so that it\ncannot be referenced after potential free. The initialization of hif_dev\nfields which are associated with remain_skb (rx_remain_len,\nrx_transfer_len and rx_pad_len) is moved after a new remain_skb is\nallocated.\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/wireless/ath/ath9k/hif_usb.c"],"versions":[{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"3fc6401fafde11712a83089fa2cc874cfd10e2cd","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"cd8316767099920a5d41feed1afab0c482a43e9f","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"f26dd69f61eff2eedf5df2d199bdd23108309947","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"61490d2710277e8a55009b7682456ae22f8087cf","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"9acdec72787af1bc8ed92711b52118c8e3e638a2","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"c766e37fccd5a5c5059be7efcd9618bf8a2c17c3","status":"affected","versionType":"git"},{"version":"44b23b488d44e56d467764ecb661830e5b02b308","lessThan":"0af54343a76263a12dbae7fafb64eb47c4a6ad38","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/net/wireless/ath/ath9k/hif_usb.c"],"versions":[{"version":"2.6.38","status":"affected"},{"version":"0","lessThan":"2.6.38","status":"unaffected","versionType":"semver"},{"version":"4.19.276","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.235","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.173","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.99","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.16","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.2.3","lessThanOrEqual":"6.2.*","status":"unaffected","versionType":"semver"},{"version":"6.3","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":"2.6.38","versionEndExcluding":"4.19.276"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"5.4.235"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"5.10.173"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"5.15.99"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"6.1.16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"6.2.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.38","versionEndExcluding":"6.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3fc6401fafde11712a83089fa2cc874cfd10e2cd"},{"url":"https://git.kernel.org/stable/c/cd8316767099920a5d41feed1afab0c482a43e9f"},{"url":"https://git.kernel.org/stable/c/f26dd69f61eff2eedf5df2d199bdd23108309947"},{"url":"https://git.kernel.org/stable/c/61490d2710277e8a55009b7682456ae22f8087cf"},{"url":"https://git.kernel.org/stable/c/9acdec72787af1bc8ed92711b52118c8e3e638a2"},{"url":"https://git.kernel.org/stable/c/c766e37fccd5a5c5059be7efcd9618bf8a2c17c3"},{"url":"https://git.kernel.org/stable/c/0af54343a76263a12dbae7fafb64eb47c4a6ad38"}],"title":"wifi: ath9k: hif_usb: clean up skbs if ath9k_hif_usb_rx_stream() fails","x_generator":{"engine":"bippy-1.2.0"}}}}
